+	  need full debugging information (like gdb or systemtap) won't
+	  be happy. But if you merely need debugging information to
+	  resolve line numbers there is no loss. Advantage is that

+	depends on DEBUG_INFO
+	help
+	  Generate debug info into separate .dwo files. This significantly
+	  reduces the build directory size for builds with DEBUG_INFO,
+	  because it stores the information only once on disk in .dwo
+	  files instead of multiple times in object files and executables.
+	  In addition the debug information is also compressed.
+
+	  Requires recent gcc (4.7+) and recent gdb/binutils.
+	  Any tool that packages or reads debug information would need
+	  to know about the .dwo files and include them.
+	  Incompatible with older versions of ccache.

+Overview
+========
+
+A Tkinter-based menuconfig implementation, based around a treeview control and
+a help display. The interface should feel familiar to people used to qconf
+('make xconfig'). Compatible with both Python 2 and Python 3.
+
+The display can be toggled between showing the full tree and showing just a
+single menu (like menuconfig.py). Only single-menu mode distinguishes between
+symbols defined with 'config' and symbols defined with 'menuconfig'.
+
+A show-all mode is available that shows invisible items in red.
+
+Supports both mouse and keyboard controls. The following keyboard shortcuts are
+available:
+
+  Ctrl-S   : Save configuration
+  Ctrl-O   : Open configuration
+  Ctrl-A   : Toggle show-all mode
+  Ctrl-N   : Toggle show-name mode
+  Ctrl-M   : Toggle single-menu mode
+  Ctrl-F, /: Open jump-to dialog
+  ESC      : Close
+
+Running
+=======
+
+guiconfig.py can be run either as a standalone executable or by calling the
+menuconfig() function with an existing Kconfig instance. The second option is a
+bit inflexible in that it will still load and save .config, etc.
+
+When run in standalone mode, the top-level Kconfig file to load can be passed
+as a command-line argument. With no argument, it defaults to "Kconfig".
+
+The KCONFIG_CONFIG environment variable specifies the .config file to load (if
+it exists) and save. If KCONFIG_CONFIG is unset, ".config" is used.
+
+When overwriting a configuration file, the old version is saved to
+<filename>.old (e.g. .config.old).
+
+$srctree is supported through Kconfiglib.
+"""
+
+# Note: There's some code duplication with menuconfig.py below, especially for
+# the help text. Maybe some of it could be moved into kconfiglib.py or a shared
+# helper script, but OTOH it's pretty nice to have things standalone and
+# customizable.

+Overview
+========
+
+Kconfiglib is a Python 2/3 library for scripting and extracting information
+from Kconfig (https://www.kernel.org/doc/Documentation/kbuild/kconfig-language.txt)
+configuration systems.
+
+See the homepage at https://github.com/ulfalizer/Kconfiglib for a longer
+overview.
+
+Since Kconfiglib 12.0.0, the library version is available in
+kconfiglib.VERSION, which is a (<major>, <minor>, <patch>) tuple, e.g.
+(12, 0, 0).
+
+
+Using Kconfiglib on the Linux kernel with the Makefile targets
+==============================================================
+
+For the Linux kernel, a handy interface is provided by the
+scripts/kconfig/Makefile patch, which can be applied with either 'git am' or
+the 'patch' utility:
+
+  $ wget -qO- https://raw.githubusercontent.com/ulfalizer/Kconfiglib/master/makefile.patch | git am
+  $ wget -qO- https://raw.githubusercontent.com/ulfalizer/Kconfiglib/master/makefile.patch | patch -p1
+
+Warning: Not passing -p1 to patch will cause the wrong file to be patched.
+
+Please tell me if the patch does not apply. It should be trivial to apply
+manually, as it's just a block of text that needs to be inserted near the other
+*conf: targets in scripts/kconfig/Makefile.
+
+Look further down for a motivation for the Makefile patch and for instructions
+on how you can use Kconfiglib without it.
+
+If you do not wish to install Kconfiglib via pip, the Makefile patch is set up
+so that you can also just clone Kconfiglib into the kernel root:
+
+  $ git clone git://github.com/ulfalizer/Kconfiglib.git
+  $ git am Kconfiglib/makefile.patch  (or 'patch -p1 < Kconfiglib/makefile.patch')
+
+Warning: The directory name Kconfiglib/ is significant in this case, because
+it's added to PYTHONPATH by the new targets in makefile.patch.
+
+The targets added by the Makefile patch are described in the following
+sections.
+
+
+make kmenuconfig
+----------------
+
+This target runs the curses menuconfig interface with Python 3. As of
+Kconfiglib 12.2.0, both Python 2 and Python 3 are supported (previously, only
+Python 3 was supported, so this was a backport).
+
+
+make guiconfig
+--------------
+
+This target runs the Tkinter menuconfig interface. Both Python 2 and Python 3
+are supported. To change the Python interpreter used, pass
+PYTHONCMD=<executable> to 'make'. The default is 'python'.
+
+
+make [ARCH=<arch>] iscriptconfig
+--------------------------------
+
+This target gives an interactive Python prompt where a Kconfig instance has
+been preloaded and is available in 'kconf'. To change the Python interpreter
+used, pass PYTHONCMD=<executable> to 'make'. The default is 'python'.
+
+To get a feel for the API, try evaluating and printing the symbols in
+kconf.defined_syms, and explore the MenuNode menu tree starting at
+kconf.top_node by following 'next' and 'list' pointers.
+
+The item contained in a menu node is found in MenuNode.item (note that this can
+be one of the constants kconfiglib.MENU and kconfiglib.COMMENT), and all
+symbols and choices have a 'nodes' attribute containing their menu nodes
+(usually only one). Printing a menu node will print its item, in Kconfig
+format.
+
+If you want to look up a symbol by name, use the kconf.syms dictionary.
+
+
+make scriptconfig SCRIPT=<script> [SCRIPT_ARG=<arg>]
+----------------------------------------------------
+
+This target runs the Python script given by the SCRIPT parameter on the
+configuration. sys.argv[1] holds the name of the top-level Kconfig file
+(currently always "Kconfig" in practice), and sys.argv[2] holds the SCRIPT_ARG
+argument, if given.
+
+See the examples/ subdirectory for example scripts.
+
+
+make dumpvarsconfig
+-------------------
+
+This target prints a list of all environment variables referenced from the
+Kconfig files, together with their values. See the
+Kconfiglib/examples/dumpvars.py script.
+
+Only environment variables that are referenced via the Kconfig preprocessor
+$(FOO) syntax are included. The preprocessor was added in Linux 4.18.
+
+
+Using Kconfiglib without the Makefile targets
+=============================================
+
+The make targets are only needed to pick up environment variables exported from
+the Kbuild makefiles and referenced inside Kconfig files, via e.g.
+'source "arch/$(SRCARCH)/Kconfig" and commands run via '$(shell,...)'.
+
+These variables are referenced as of writing (Linux 4.18), together with sample
+values:
+
+  srctree          (.)
+  ARCH             (x86)
+  SRCARCH          (x86)
+  KERNELVERSION    (4.18.0)
+  CC               (gcc)
+  HOSTCC           (gcc)
+  HOSTCXX          (g++)
+  CC_VERSION_TEXT  (gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0)
+
+Older kernels only reference ARCH, SRCARCH, and KERNELVERSION.
+
+If your kernel is recent enough (4.18+), you can get a list of referenced
+environment variables via 'make dumpvarsconfig' (see above). Note that this
+command is added by the Makefile patch.
+
+To run Kconfiglib without the Makefile patch, set the environment variables
+manually:
+
+  $ srctree=. ARCH=x86 SRCARCH=x86 KERNELVERSION=`make kernelversion` ... python(3)
+  >>> import kconfiglib
+  >>> kconf = kconfiglib.Kconfig()  # filename defaults to "Kconfig"
+
+Search the top-level Makefile for "Additional ARCH settings" to see other
+possibilities for ARCH and SRCARCH.
+
+
+Intro to symbol values
+======================
+
+Kconfiglib has the same assignment semantics as the C implementation.
+
+Any symbol can be assigned a value by the user (via Kconfig.load_config() or
+Symbol.set_value()), but this user value is only respected if the symbol is
+visible, which corresponds to it (currently) being visible in the menuconfig
+interface.
+
+For symbols with prompts, the visibility of the symbol is determined by the
+condition on the prompt. Symbols without prompts are never visible, so setting
+a user value on them is pointless. A warning will be printed by default if
+Symbol.set_value() is called on a promptless symbol. Assignments to promptless
+symbols are normal within a .config file, so no similar warning will be printed
+by load_config().
+
+Dependencies from parents and 'if'/'depends on' are propagated to properties,
+including prompts, so these two configurations are logically equivalent:
+
+(1)
+
+  menu "menu"
+      depends on A
+
+  if B
+
+  config FOO
+      tristate "foo" if D
+      default y
+      depends on C
+
+  endif
+
+  endmenu
+
+(2)
+
+  menu "menu"
+      depends on A
+
+  config FOO
+      tristate "foo" if A && B && C && D
+      default y if A && B && C
+
+  endmenu
+
+In this example, A && B && C && D (the prompt condition) needs to be non-n for
+FOO to be visible (assignable). If its value is m, the symbol can only be
+assigned the value m: The visibility sets an upper bound on the value that can
+be assigned by the user, and any higher user value will be truncated down.
+
+'default' properties are independent of the visibility, though a 'default' will
+often get the same condition as the prompt due to dependency propagation.
+'default' properties are used if the symbol is not visible or has no user
+value.
+
+Symbols with no user value (or that have a user value but are not visible) and
+no (active) 'default' default to n for bool/tristate symbols, and to the empty
+string for other symbol types.
+
+'select' works similarly to symbol visibility, but sets a lower bound on the
+value of the symbol. The lower bound is determined by the value of the
+select*ing* symbol. 'select' does not respect visibility, so non-visible
+symbols can be forced to a particular (minimum) value by a select as well.
+
+For non-bool/tristate symbols, it only matters whether the visibility is n or
+non-n: m visibility acts the same as y visibility.
+
+Conditions on 'default' and 'select' work in mostly intuitive ways. If the
+condition is n, the 'default' or 'select' is disabled. If it is m, the
+'default' or 'select' value (the value of the selecting symbol) is truncated
+down to m.
+
+When writing a configuration with Kconfig.write_config(), only symbols that are
+visible, have an (active) default, or are selected will get written out (note
+that this includes all symbols that would accept user values). Kconfiglib
+matches the .config format produced by the C implementations down to the
+character. This eases testing.
+
+For a visible bool/tristate symbol FOO with value n, this line is written to
+.config:
+
+    # CONFIG_FOO is not set
+
+The point is to remember the user n selection (which might differ from the
+default value the symbol would get), while at the same sticking to the rule
+that undefined corresponds to n (.config uses Makefile format, making the line
+above a comment). When the .config file is read back in, this line will be
+treated the same as the following assignment:
+
+    CONFIG_FOO=n
+
+In Kconfiglib, the set of (currently) assignable values for a bool/tristate
+symbol appear in Symbol.assignable. For other symbol types, just check if
+sym.visibility is non-0 (non-n) to see whether the user value will have an
+effect.
+
+
+Intro to the menu tree
+======================
+
+The menu structure, as seen in e.g. menuconfig, is represented by a tree of
+MenuNode objects. The top node of the configuration corresponds to an implicit
+top-level menu, the title of which is shown at the top in the standard
+menuconfig interface. (The title is also available in Kconfig.mainmenu_text in
+Kconfiglib.)
+
+The top node is found in Kconfig.top_node. From there, you can visit child menu
+nodes by following the 'list' pointer, and any following menu nodes by
+following the 'next' pointer. Usually, a non-None 'list' pointer indicates a
+menu or Choice, but menu nodes for symbols can sometimes have a non-None 'list'
+pointer too due to submenus created implicitly from dependencies.
+
+MenuNode.item is either a Symbol or a Choice object, or one of the constants
+MENU and COMMENT. The prompt of the menu node can be found in MenuNode.prompt,
+which also holds the title for menus and comments. For Symbol and Choice,
+MenuNode.help holds the help text (if any, otherwise None).
+
+Most symbols will only have a single menu node. A symbol defined in multiple
+locations will have one menu node for each location. The list of menu nodes for
+a Symbol or Choice can be found in the Symbol/Choice.nodes attribute.
+
+Note that prompts and help texts for symbols and choices are stored in their
+menu node(s) rather than in the Symbol or Choice objects themselves. This makes
+it possible to define a symbol in multiple locations with a different prompt or
+help text in each location. To get the help text or prompt for a symbol with a
+single menu node, do sym.nodes[0].help and sym.nodes[0].prompt, respectively.
+The prompt is a (text, condition) tuple, where condition determines the
+visibility (see 'Intro to expressions' below).
+
+This organization mirrors the C implementation. MenuNode is called
+'struct menu' there, but I thought "menu" was a confusing name.
+
+It is possible to give a Choice a name and define it in multiple locations,
+hence why Choice.nodes is also a list.
+
+As a convenience, the properties added at a particular definition location are
+available on the MenuNode itself, in e.g. MenuNode.defaults. This is helpful
+when generating documentation, so that symbols/choices defined in multiple
+locations can be shown with the correct properties at each location.
+
+
+Intro to expressions
+====================
+
+Expressions can be evaluated with the expr_value() function and printed with
+the expr_str() function (these are used internally as well). Evaluating an
+expression always yields a tristate value, where n, m, and y are represented as
+0, 1, and 2, respectively.
+
+The following table should help you figure out how expressions are represented.
+A, B, C, ... are symbols (Symbol instances), NOT is the kconfiglib.NOT
+constant, etc.
+
+Expression            Representation
+----------            --------------
+A                     A
+"A"                   A (constant symbol)
+!A                    (NOT, A)
+A && B                (AND, A, B)
+A && B && C           (AND, A, (AND, B, C))
+A || B                (OR, A, B)
+A || (B && C && D)    (OR, A, (AND, B, (AND, C, D)))
+A = B                 (EQUAL, A, B)
+A != "foo"            (UNEQUAL, A, foo (constant symbol))
+A && B = C && D       (AND, A, (AND, (EQUAL, B, C), D))
+n                     Kconfig.n (constant symbol)
+m                     Kconfig.m (constant symbol)
+y                     Kconfig.y (constant symbol)
+"y"                   Kconfig.y (constant symbol)
+
+Strings like "foo" in 'default "foo"' or 'depends on SYM = "foo"' are
+represented as constant symbols, so the only values that appear in expressions
+are symbols***. This mirrors the C implementation.
+
+***For choice symbols, the parent Choice will appear in expressions as well,
+but it's usually invisible as the value interfaces of Symbol and Choice are
+identical. This mirrors the C implementation and makes different choice modes
+"just work".
+
+Manual evaluation examples:
+
+  - The value of A && B is min(A.tri_value, B.tri_value)
+
+  - The value of A || B is max(A.tri_value, B.tri_value)
+
+  - The value of !A is 2 - A.tri_value
+
+  - The value of A = B is 2 (y) if A.str_value == B.str_value, and 0 (n)
+    otherwise. Note that str_value is used here instead of tri_value.
+
+    For constant (as well as undefined) symbols, str_value matches the name of
+    the symbol. This mirrors the C implementation and explains why
+    'depends on SYM = "foo"' above works as expected.
+
+n/m/y are automatically converted to the corresponding constant symbols
+"n"/"m"/"y" (Kconfig.n/m/y) during parsing.
+
+Kconfig.const_syms is a dictionary like Kconfig.syms but for constant symbols.
+
+If a condition is missing (e.g., <cond> when the 'if <cond>' is removed from
+'default A if <cond>'), it is actually Kconfig.y. The standard __str__()
+functions just avoid printing 'if y' conditions to give cleaner output.
+
+
+Kconfig extensions
+==================
+
+Kconfiglib includes a couple of Kconfig extensions:
+
+'source' with relative path
+---------------------------
+
+The 'rsource' statement sources Kconfig files with a path relative to directory
+of the Kconfig file containing the 'rsource' statement, instead of relative to
+the project root.
+
+Consider following directory tree:
+
+  Project
+  +--Kconfig
+  |
+  +--src
+     +--Kconfig
+     |
+     +--SubSystem1
+        +--Kconfig
+        |
+        +--ModuleA
+           +--Kconfig
+
+In this example, assume that src/SubSystem1/Kconfig wants to source
+src/SubSystem1/ModuleA/Kconfig.
+
+With 'source', this statement would be used:
+
+  source "src/SubSystem1/ModuleA/Kconfig"
+
+With 'rsource', this turns into
+
+  rsource "ModuleA/Kconfig"
+
+If an absolute path is given to 'rsource', it acts the same as 'source'.
+
+'rsource' can be used to create "position-independent" Kconfig trees that can
+be moved around freely.
+
+
+Globbing 'source'
+-----------------
+
+'source' and 'rsource' accept glob patterns, sourcing all matching Kconfig
+files. They require at least one matching file, raising a KconfigError
+otherwise.
+
+For example, the following statement might source sub1/foofoofoo and
+sub2/foobarfoo:
+
+  source "sub[12]/foo*foo"
+
+The glob patterns accepted are the same as for the standard glob.glob()
+function.
+
+Two additional statements are provided for cases where it's acceptable for a
+pattern to match no files: 'osource' and 'orsource' (the o is for "optional").
+
+For example, the following statements will be no-ops if neither "foo" nor any
+files matching "bar*" exist:
+
+  osource "foo"
+  osource "bar*"
+
+'orsource' does a relative optional source.
+
+'source' and 'osource' are analogous to 'include' and '-include' in Make.
+
+
+Generalized def_* keywords
+--------------------------
+
+def_int, def_hex, and def_string are available in addition to def_bool and
+def_tristate, allowing int, hex, and string symbols to be given a type and a
+default at the same time.
+
+
+Extra optional warnings
+-----------------------
+
+Some optional warnings can be controlled via environment variables:
+
+  - KCONFIG_WARN_UNDEF: If set to 'y', warnings will be generated for all
+    references to undefined symbols within Kconfig files. The only gotcha is
+    that all hex literals must be prefixed with "0x" or "0X", to make it
+    possible to distinguish them from symbol references.
+
+    Some projects (e.g. the Linux kernel) use multiple Kconfig trees with many
+    shared Kconfig files, leading to some safe undefined symbol references.
+    KCONFIG_WARN_UNDEF is useful in projects that only have a single Kconfig
+    tree though.
+
+    KCONFIG_STRICT is an older alias for this environment variable, supported
+    for backwards compatibility.
+
+  - KCONFIG_WARN_UNDEF_ASSIGN: If set to 'y', warnings will be generated for
+    all assignments to undefined symbols within .config files. By default, no
+    such warnings are generated.
+
+    This warning can also be enabled/disabled via the Kconfig.warn_assign_undef
+    variable.
+
+
+Preprocessor user functions defined in Python
+---------------------------------------------
+
+Preprocessor functions can be defined in Python, which makes it simple to
+integrate information from existing Python tools into Kconfig (e.g. to have
+Kconfig symbols depend on hardware information stored in some other format).
+
+Putting a Python module named kconfigfunctions(.py) anywhere in sys.path will
+cause it to be imported by Kconfiglib (in Kconfig.__init__()). Note that
+sys.path can be customized via PYTHONPATH, and includes the directory of the
+module being run by default, as well as installation directories.
+
+If the KCONFIG_FUNCTIONS environment variable is set, it gives a different
+module name to use instead of 'kconfigfunctions'.
+
+The imported module is expected to define a global dictionary named 'functions'
+that maps function names to Python functions, as follows:
+
+  def my_fn(kconf, name, arg_1, arg_2, ...):
+      # kconf:
+      #   Kconfig instance
+      #
+      # name:
+      #   Name of the user-defined function ("my-fn"). Think argv[0].
+      #
+      # arg_1, arg_2, ...:
+      #   Arguments passed to the function from Kconfig (strings)
+      #
+      # Returns a string to be substituted as the result of calling the
+      # function
+      ...
+
+  def my_other_fn(kconf, name, arg_1, arg_2, ...):
+      ...
+
+  functions = {
+      "my-fn":       (my_fn,       <min.args>, <max.args>/None),
+      "my-other-fn": (my_other_fn, <min.args>, <max.args>/None),
+      ...
+  }
+
+  ...
+
+<min.args> and <max.args> are the minimum and maximum number of arguments
+expected by the function (excluding the implicit 'name' argument). If
+<max.args> is None, there is no upper limit to the number of arguments. Passing
+an invalid number of arguments will generate a KconfigError exception.
+
+Functions can access the current parsing location as kconf.filename/linenr.
+Accessing other fields of the Kconfig object is not safe. See the warning
+below.
+
+Keep in mind that for a variable defined like 'foo = $(fn)', 'fn' will be
+called only when 'foo' is expanded. If 'fn' uses the parsing location and the
+intent is to use the location of the assignment, you want 'foo := $(fn)'
+instead, which calls the function immediately.
+
+Once defined, user functions can be called from Kconfig in the same way as
+other preprocessor functions:
+
+    config FOO
+        ...
+        depends on $(my-fn,arg1,arg2)
+
+If my_fn() returns "n", this will result in
+
+    config FOO
+        ...
+        depends on n
+
+Warning
+*******
+
+User-defined preprocessor functions are called as they're encountered at parse
+time, before all Kconfig files have been processed, and before the menu tree
+has been finalized. There are no guarantees that accessing Kconfig symbols or
+the menu tree via the 'kconf' parameter will work, and it could potentially
+lead to a crash.
+
+Preferably, user-defined functions should be stateless.

+class Kconfig(object):
+    """
+    Represents a Kconfig configuration, e.g. for x86 or ARM. This is the set of
+    symbols, choices, and menu nodes appearing in the configuration. Creating
+    any number of Kconfig objects (including for different architectures) is
+    safe. Kconfiglib doesn't keep any global state.
+
+    The following attributes are available. They should be treated as
+    read-only, and some are implemented through @property magic.
+
+    syms:
+      A dictionary with all symbols in the configuration, indexed by name. Also
+      includes all symbols that are referenced in expressions but never
+      defined, except for constant (quoted) symbols.
+
+      Undefined symbols can be recognized by Symbol.nodes being empty -- see
+      the 'Intro to the menu tree' section in the module docstring.
+
+    const_syms:
+      A dictionary like 'syms' for constant (quoted) symbols
+
+    named_choices:
+      A dictionary like 'syms' for named choices (choice FOO)
+
+    defined_syms:
+      A list with all defined symbols, in the same order as they appear in the
+      Kconfig files. Symbols defined in multiple locations appear multiple
+      times.
+
+      Note: You probably want to use 'unique_defined_syms' instead. This
+      attribute is mostly maintained for backwards compatibility.
+
+    unique_defined_syms:
+      A list like 'defined_syms', but with duplicates removed. Just the first
+      instance is kept for symbols defined in multiple locations. Kconfig order
+      is preserved otherwise.
+
+      Using this attribute instead of 'defined_syms' can save work, and
+      automatically gives reasonable behavior when writing configuration output
+      (symbols defined in multiple locations only generate output once, while
+      still preserving Kconfig order for readability).
+
+    choices:
+      A list with all choices, in the same order as they appear in the Kconfig
+      files.
+
+      Note: You probably want to use 'unique_choices' instead. This attribute
+      is mostly maintained for backwards compatibility.
+
+    unique_choices:
+      Analogous to 'unique_defined_syms', for choices. Named choices can have
+      multiple definition locations.
+
+    menus:
+      A list with all menus, in the same order as they appear in the Kconfig
+      files
+
+    comments:
+      A list with all comments, in the same order as they appear in the Kconfig
+      files
+
+    kconfig_filenames:
+      A list with the filenames of all Kconfig files included in the
+      configuration, relative to $srctree (or relative to the current directory
+      if $srctree isn't set), except absolute paths (e.g.
+      'source "/foo/Kconfig"') are kept as-is.
+
+      The files are listed in the order they are source'd, starting with the
+      top-level Kconfig file. If a file is source'd multiple times, it will
+      appear multiple times. Use set() to get unique filenames.
+
+      Note that Kconfig.sync_deps() already indirectly catches any file
+      modifications that change configuration output.
+
+    env_vars:
+      A set() with the names of all environment variables referenced in the
+      Kconfig files.
+
+      Only environment variables referenced with the preprocessor $(FOO) syntax
+      will be registered. The older $FOO syntax is only supported for backwards
+      compatibility.
+
+      Also note that $(FOO) won't be registered unless the environment variable
+      $FOO is actually set. If it isn't, $(FOO) is an expansion of an unset
+      preprocessor variable (which gives the empty string).
+
+      Another gotcha is that environment variables referenced in the values of
+      recursively expanded preprocessor variables (those defined with =) will
+      only be registered if the variable is actually used (expanded) somewhere.
+
+      The note from the 'kconfig_filenames' documentation applies here too.
+
+    n/m/y:
+      The predefined constant symbols n/m/y. Also available in const_syms.
+
+    modules:
+      The Symbol instance for the modules symbol. Currently hardcoded to
+      MODULES, which is backwards compatible. Kconfiglib will warn if
+      'option modules' is set on some other symbol. Tell me if you need proper
+      'option modules' support.
+
+      'modules' is never None. If the MODULES symbol is not explicitly defined,
+      its tri_value will be 0 (n), as expected.
+
+      A simple way to enable modules is to do 'kconf.modules.set_value(2)'
+      (provided the MODULES symbol is defined and visible). Modules are
+      disabled by default in the kernel Kconfig files as of writing, though
+      nearly all defconfig files enable them (with 'CONFIG_MODULES=y').
+
+    defconfig_list:
+      The Symbol instance for the 'option defconfig_list' symbol, or None if no
+      defconfig_list symbol exists. The defconfig filename derived from this
+      symbol can be found in Kconfig.defconfig_filename.
+
+    defconfig_filename:
+      The filename given by the defconfig_list symbol. This is taken from the
+      first 'default' with a satisfied condition where the specified file
+      exists (can be opened for reading). If a defconfig file foo/defconfig is
+      not found and $srctree was set when the Kconfig was created,
+      $srctree/foo/defconfig is looked up as well.
+
+      'defconfig_filename' is None if either no defconfig_list symbol exists,
+      or if the defconfig_list symbol has no 'default' with a satisfied
+      condition that specifies a file that exists.
+
+      Gotcha: scripts/kconfig/Makefile might pass --defconfig=<defconfig> to
+      scripts/kconfig/conf when running e.g. 'make defconfig'. This option
+      overrides the defconfig_list symbol, meaning defconfig_filename might not
+      always match what 'make defconfig' would use.
+
+    top_node:
+      The menu node (see the MenuNode class) of the implicit top-level menu.
+      Acts as the root of the menu tree.
+
+    mainmenu_text:
+      The prompt (title) of the top menu (top_node). Defaults to "Main menu".
+      Can be changed with the 'mainmenu' statement (see kconfig-language.txt).
+
+    variables:
+      A dictionary with all preprocessor variables, indexed by name. See the
+      Variable class.
+
+    warn:
+      Set this variable to True/False to enable/disable warnings. See
+      Kconfig.__init__().
+
+      When 'warn' is False, the values of the other warning-related variables
+      are ignored.
+
+      This variable as well as the other warn* variables can be read to check
+      the current warning settings.
+
+    warn_to_stderr:
+      Set this variable to True/False to enable/disable warnings on stderr. See
+      Kconfig.__init__().
+
+    warn_assign_undef:
+      Set this variable to True to generate warnings for assignments to
+      undefined symbols in configuration files.
+
+      This variable is False by default unless the KCONFIG_WARN_UNDEF_ASSIGN
+      environment variable was set to 'y' when the Kconfig instance was
+      created.
+
+    warn_assign_override:
+      Set this variable to True to generate warnings for multiple assignments
+      to the same symbol in configuration files, where the assignments set
+      different values (e.g. CONFIG_FOO=m followed by CONFIG_FOO=y, where the
+      last value would get used).
+
+      This variable is True by default. Disabling it might be useful when
+      merging configurations.
+
+    warn_assign_redun:
+      Like warn_assign_override, but for multiple assignments setting a symbol
+      to the same value.
+
+      This variable is True by default. Disabling it might be useful when
+      merging configurations.
+
+    warnings:
+      A list of strings containing all warnings that have been generated, for
+      cases where more flexibility is needed.
+
+      See the 'warn_to_stderr' parameter to Kconfig.__init__() and the
+      Kconfig.warn_to_stderr variable as well. Note that warnings still get
+      added to Kconfig.warnings when 'warn_to_stderr' is True.
+
+      Just as for warnings printed to stderr, only warnings that are enabled
+      will get added to Kconfig.warnings. See the various Kconfig.warn*
+      variables.
+
+    missing_syms:
+      A list with (name, value) tuples for all assignments to undefined symbols
+      within the most recently loaded .config file(s). 'name' is the symbol
+      name without the 'CONFIG_' prefix. 'value' is a string that gives the
+      right-hand side of the assignment verbatim.
+
+      See Kconfig.load_config() as well.
+
+    srctree:
+      The value the $srctree environment variable had when the Kconfig instance
+      was created, or the empty string if $srctree wasn't set. This gives nice
+      behavior with os.path.join(), which treats "" as the current directory,
+      without adding "./".
+
+      Kconfig files are looked up relative to $srctree (unless absolute paths
+      are used), and .config files are looked up relative to $srctree if they
+      are not found in the current directory. This is used to support
+      out-of-tree builds. The C tools use this environment variable in the same
+      way.
+
+      Changing $srctree after creating the Kconfig instance has no effect. Only
+      the value when the configuration is loaded matters. This avoids surprises
+      if multiple configurations are loaded with different values for $srctree.
+
+    config_prefix:
+      The value the CONFIG_ environment variable had when the Kconfig instance
+      was created, or "CONFIG_" if CONFIG_ wasn't set. This is the prefix used
+      (and expected) on symbol names in .config files and C headers. Used in
+      the same way in the C tools.
+
+    config_header:
+      The value the KCONFIG_CONFIG_HEADER environment variable had when the
+      Kconfig instance was created, or the empty string if
+      KCONFIG_CONFIG_HEADER wasn't set. This string is inserted verbatim at the
+      beginning of configuration files. See write_config().
+
+    header_header:
+      The value the KCONFIG_AUTOHEADER_HEADER environment variable had when the
+      Kconfig instance was created, or the empty string if
+      KCONFIG_AUTOHEADER_HEADER wasn't set. This string is inserted verbatim at
+      the beginning of header files. See write_autoconf().
+
+    filename/linenr:
+      The current parsing location, for use in Python preprocessor functions.
+      See the module docstring.

+        Creates a new Kconfig object by parsing Kconfig files.
+        Note that Kconfig files are not the same as .config files (which store
+        configuration symbol values).
+
+        See the module docstring for some environment variables that influence
+        default warning settings (KCONFIG_WARN_UNDEF and
+        KCONFIG_WARN_UNDEF_ASSIGN).
+
+        Raises KconfigError on syntax/semantic errors, and OSError or (possibly
+        a subclass of) IOError on IO errors ('errno', 'strerror', and
+        'filename' are available). Note that IOError is an alias for OSError on
+        Python 3, so it's enough to catch OSError there. If you need Python 2/3
+        compatibility, it's easiest to catch EnvironmentError, which is a
+        common base class of OSError/IOError on Python 2 and an alias for
+        OSError on Python 3.
+
+        filename (default: "Kconfig"):
+          The Kconfig file to load. For the Linux kernel, you'll want "Kconfig"
+          from the top-level directory, as environment variables will make sure
+          the right Kconfig is included from there (arch/$SRCARCH/Kconfig as of
+          writing).
+
+          If $srctree is set, 'filename' will be looked up relative to it.
+          $srctree is also used to look up source'd files within Kconfig files.
+          See the class documentation.
+
+          If you are using Kconfiglib via 'make scriptconfig', the filename of
+          the base base Kconfig file will be in sys.argv[1]. It's currently
+          always "Kconfig" in practice.
+
+        warn (default: True):
+          True if warnings related to this configuration should be generated.
+          This can be changed later by setting Kconfig.warn to True/False. It
+          is provided as a constructor argument since warnings might be
+          generated during parsing.
+
+          See the other Kconfig.warn_* variables as well, which enable or
+          suppress certain warnings when warnings are enabled.
+
+          All generated warnings are added to the Kconfig.warnings list. See
+          the class documentation.
+
+        warn_to_stderr (default: True):
+          True if warnings should be printed to stderr in addition to being
+          added to Kconfig.warnings.
+
+          This can be changed later by setting Kconfig.warn_to_stderr to
+          True/False.
+
+        encoding (default: "utf-8"):
+          The encoding to use when reading and writing files, and when decoding
+          output from commands run via $(shell). If None, the encoding
+          specified in the current locale will be used.
+
+          The "utf-8" default avoids exceptions on systems that are configured
+          to use the C locale, which implies an ASCII encoding.
+
+          This parameter has no effect on Python 2, due to implementation
+          issues (regular strings turning into Unicode strings, which are
+          distinct in Python 2). Python 2 doesn't decode regular strings
+          anyway.
+
+          Related PEP: https://www.python.org/dev/peps/pep-0538/
+
+        suppress_traceback (default: False):
+          Helper for tools. When True, any EnvironmentError or KconfigError
+          generated during parsing is caught, the exception message is printed
+          to stderr together with the command name, and sys.exit(1) is called
+          (which generates SystemExit).
+
+          This hides the Python traceback for "expected" errors like syntax
+          errors in Kconfig files.
+
+          Other exceptions besides EnvironmentError and KconfigError are still
+          propagated when suppress_traceback is True.

+        For each symbol, the Symbol.user_value attribute holds the value the
+        symbol was assigned in the .config file (if any). The user value might
+        differ from Symbol.str/tri_value if there are unsatisfied dependencies.
+
+        Calling this function also updates the Kconfig.missing_syms attribute
+        with a list of all assignments to undefined symbols within the

+
+            2. If the path from (1.) doesn't exist, the configuration file
+               given by kconf.defconfig_filename is loaded instead, which is
+               derived from the 'option defconfig_list' symbol.
+
+            3. If (1.) and (2.) fail to find a configuration file to load, no
+               configuration file is loaded, and symbols retain their current
+               values (e.g., their default values). This is not an error.

+        Creates or updates a directory structure that can be used to avoid
+        doing a full rebuild whenever the configuration is changed, mirroring
+        include/config/ in the kernel.
+
+        This function is intended to be called during each build, before
+        compiling source files that depend on configuration symbols.
+
+        See the Kconfig.__init__() docstring for raised exceptions
+        (OSError/IOError). KconfigError is never raised here.
+
+        path:
+          Path to directory
+
+        sync_deps(path) does the following:
+
+          1. If the directory <path> does not exist, it is created.
+
+          2. If <path>/auto.conf exists, old symbol values are loaded from it,
+             which are then compared against the current symbol values. If a
+             symbol has changed value (would generate different output in
+             autoconf.h compared to before), the change is signaled by
+             touch'ing a file corresponding to the symbol.
+
+             The first time sync_deps() is run on a directory, <path>/auto.conf
+             won't exist, and no old symbol values will be available. This
+             logically has the same effect as updating the entire
+             configuration.
+
+             The path to a symbol's file is calculated from the symbol's name
+             by replacing all '_' with '/' and appending '.h'. For example, the
+             symbol FOO_BAR_BAZ gets the file <path>/foo/bar/baz.h, and FOO
+             gets the file <path>/foo.h.
+
+             This scheme matches the C tools. The point is to avoid having a
+             single directory with a huge number of files, which the underlying
+             filesystem might not handle well.
+
+          3. A new auto.conf with the current symbol values is written, to keep
+             track of them for the next build.
+
+             If auto.conf exists and its contents is identical to what would
+             get written out, it is left untouched. This avoids updating file
+             metadata like the modification time and possibly triggering
+             redundant work in build tools.
+
+
+        The last piece of the puzzle is knowing what symbols each source file
+        depends on. Knowing that, dependencies can be added from source files
+        to the files corresponding to the symbols they depends on. The source
+        file will then get recompiled (only) when the symbol value changes
+        (provided sync_deps() is run first during each build).
+
+        The tool in the kernel that extracts symbol dependencies from source
+        files is scripts/basic/fixdep.c. Missing symbol files also correspond
+        to "not changed", which fixdep deals with by using the $(wildcard) Make
+        function when adding symbol prerequisites to source files.
+
+        In case you need a different scheme for your project, the sync_deps()
+        implementation can be used as a template.

+    Represents a configuration symbol:
+
+      (menu)config FOO
+          ...
+
+    The following attributes are available. They should be viewed as read-only,
+    and some are implemented through @property magic (but are still efficient
+    to access due to internal caching).
+
+    Note: Prompts, help texts, and locations are stored in the Symbol's
+    MenuNode(s) rather than in the Symbol itself. Check the MenuNode class and
+    the Symbol.nodes attribute. This organization matches the C tools.
+
+    name:
+      The name of the symbol, e.g. "FOO" for 'config FOO'.
+
+    type:
+      The type of the symbol. One of BOOL, TRISTATE, STRING, INT, HEX, UNKNOWN.
+      UNKNOWN is for undefined symbols, (non-special) constant symbols, and
+      symbols defined without a type.
+
+      When running without modules (MODULES having the value n), TRISTATE
+      symbols magically change type to BOOL. This also happens for symbols
+      within choices in "y" mode. This matches the C tools, and makes sense for
+      menuconfig-like functionality.
+
+    orig_type:
+      The type as given in the Kconfig file, without any magic applied. Used
+      when printing the symbol.
+
+    tri_value:
+      The tristate value of the symbol as an integer. One of 0, 1, 2,
+      representing n, m, y. Always 0 (n) for non-bool/tristate symbols.
+
+      This is the symbol value that's used outside of relation expressions
+      (A, !A, A && B, A || B).
+
+    str_value:
+      The value of the symbol as a string. Gives the value for string/int/hex
+      symbols. For bool/tristate symbols, gives "n", "m", or "y".
+
+      This is the symbol value that's used in relational expressions
+      (A = B, A != B, etc.)
+
+      Gotcha: For int/hex symbols, the exact format of the value is often
+      preserved (e.g. when writing a .config file), hence why you can't get it
+      directly as an int. Do int(int_sym.str_value) or
+      int(hex_sym.str_value, 16) to get the integer value.
+
+    user_value:
+      The user value of the symbol. None if no user value has been assigned
+      (via Kconfig.load_config() or Symbol.set_value()).
+
+      Holds 0, 1, or 2 for bool/tristate symbols, and a string for the other
+      symbol types.
+
+      WARNING: Do not assign directly to this. It will break things. Use
+      Symbol.set_value().
+
+    assignable:
+      A tuple containing the tristate user values that can currently be
+      assigned to the symbol (that would be respected), ordered from lowest (0,
+      representing n) to highest (2, representing y). This corresponds to the
+      selections available in the menuconfig interface. The set of assignable
+      values is calculated from the symbol's visibility and selects/implies.
+
+      Returns the empty set for non-bool/tristate symbols and for symbols with
+      visibility n. The other possible values are (0, 2), (0, 1, 2), (1, 2),
+      (1,), and (2,). A (1,) or (2,) result means the symbol is visible but
+      "locked" to m or y through a select, perhaps in combination with the
+      visibility. menuconfig represents this as -M- and -*-, respectively.
+
+      For string/hex/int symbols, check if Symbol.visibility is non-0 (non-n)
+      instead to determine if the value can be changed.
+
+      Some handy 'assignable' idioms:
+
+        # Is 'sym' an assignable (visible) bool/tristate symbol?
+        if sym.assignable:
+            # What's the highest value it can be assigned? [-1] in Python
+            # gives the last element.
+            sym_high = sym.assignable[-1]
+
+            # The lowest?
+            sym_low = sym.assignable[0]
+
+            # Can the symbol be set to at least m?
+            if sym.assignable[-1] >= 1:
+                ...
+
+        # Can the symbol be set to m?
+        if 1 in sym.assignable:
+            ...
+
+    visibility:
+      The visibility of the symbol. One of 0, 1, 2, representing n, m, y. See
+      the module documentation for an overview of symbol values and visibility.
+
+    config_string:
+      The .config assignment string that would get written out for the symbol
+      by Kconfig.write_config(). Returns the empty string if no .config
+      assignment would get written out.
+
+      In general, visible symbols, symbols with (active) defaults, and selected
+      symbols get written out. This includes all non-n-valued bool/tristate
+      symbols, and all visible string/int/hex symbols.
+
+      Symbols with the (no longer needed) 'option env=...' option generate no
+      configuration output, and neither does the special
+      'option defconfig_list' symbol.
+
+      Tip: This field is useful when generating custom configuration output,
+      even for non-.config-like formats. To write just the symbols that would
+      get written out to .config files, do this:
+
+        if sym.config_string:
+            *Write symbol, e.g. by looking sym.str_value*
+
+      This is a superset of the symbols written out by write_autoconf().
+      That function skips all n-valued symbols.
+
+      There usually won't be any great harm in just writing all symbols either,
+      though you might get some special symbols and possibly some "redundant"
+      n-valued symbol entries in there.
+
+    name_and_loc:
+      Holds a string like
+
+        "MY_SYMBOL (defined at foo/Kconfig:12, bar/Kconfig:14)"
+
+      , giving the name of the symbol and its definition location(s).
+
+      If the symbol is undefined, the location is given as "(undefined)".
+
+    nodes:
+      A list of MenuNodes for this symbol. Will contain a single MenuNode for
+      most symbols. Undefined and constant symbols have an empty nodes list.
+      Symbols defined in multiple locations get one node for each location.
+
+    choice:
+      Holds the parent Choice for choice symbols, and None for non-choice
+      symbols. Doubles as a flag for whether a symbol is a choice symbol.
+
+    defaults:
+      List of (default, cond) tuples for the symbol's 'default' properties. For
+      example, 'default A && B if C || D' is represented as
+      ((AND, A, B), (OR, C, D)). If no condition was given, 'cond' is
+      self.kconfig.y.
+
+      Note that 'depends on' and parent dependencies are propagated to
+      'default' conditions.
+
+    selects:
+      List of (symbol, cond) tuples for the symbol's 'select' properties. For
+      example, 'select A if B && C' is represented as (A, (AND, B, C)). If no
+      condition was given, 'cond' is self.kconfig.y.
+
+      Note that 'depends on' and parent dependencies are propagated to 'select'
+      conditions.
+
+    implies:
+      Like 'selects', for imply.
+
+    ranges:
+      List of (low, high, cond) tuples for the symbol's 'range' properties. For
+      example, 'range 1 2 if A' is represented as (1, 2, A). If there is no
+      condition, 'cond' is self.kconfig.y.
+
+      Note that 'depends on' and parent dependencies are propagated to 'range'
+      conditions.
+
+      Gotcha: 1 and 2 above will be represented as (undefined) Symbols rather
+      than plain integers. Undefined symbols get their name as their string
+      value, so this works out. The C tools work the same way.
+
+    orig_defaults:
+    orig_selects:
+    orig_implies:
+    orig_ranges:
+      See the corresponding attributes on the MenuNode class.
+
+    rev_dep:
+      Reverse dependency expression from other symbols selecting this symbol.
+      Multiple selections get ORed together. A condition on a select is ANDed
+      with the selecting symbol.
+
+      For example, if A has 'select FOO' and B has 'select FOO if C', then
+      FOO's rev_dep will be (OR, A, (AND, B, C)).
+
+    weak_rev_dep:
+      Like rev_dep, for imply.
+
+    direct_dep:
+      The direct ('depends on') dependencies for the symbol, or self.kconfig.y
+      if there are no direct dependencies.
+
+      This attribute includes any dependencies from surrounding menus and ifs.
+      Those get propagated to the direct dependencies, and the resulting direct
+      dependencies in turn get propagated to the conditions of all properties.
+
+      If the symbol is defined in multiple locations, the dependencies from the
+      different locations get ORed together.
+
+    referenced:
+      A set() with all symbols and choices referenced in the properties and
+      property conditions of the symbol.
+
+      Also includes dependencies from surrounding menus and ifs, because those
+      get propagated to the symbol (see the 'Intro to symbol values' section in
+      the module docstring).
+
+      Choices appear in the dependencies of choice symbols.
+
+      For the following definitions, only B and not C appears in A's
+      'referenced'. To get transitive references, you'll have to recursively
+      expand 'references' until no new items appear.
+
+        config A
+                bool
+                depends on B
+
+        config B
+                bool
+                depends on C
+
+        config C
+                bool
+
+      See the Symbol.direct_dep attribute if you're only interested in the
+      direct dependencies of the symbol (its 'depends on'). You can extract the
+      symbols in it with the global expr_items() function.
+
+    env_var:
+      If the Symbol has an 'option env="FOO"' option, this contains the name
+      ("FOO") of the environment variable. None for symbols without no
+      'option env'.
+
+      'option env="FOO"' acts like a 'default' property whose value is the
+      value of $FOO.
+
+      Symbols with 'option env' are never written out to .config files, even if
+      they are visible. env_var corresponds to a flag called SYMBOL_AUTO in the
+      C implementation.
+
+    is_allnoconfig_y:
+      True if the symbol has 'option allnoconfig_y' set on it. This has no
+      effect internally (except when printing symbols), but can be checked by
+      scripts.
+
+    is_constant:
+      True if the symbol is a constant (quoted) symbol.
+
+    kconfig:
+      The Kconfig instance this symbol is from.

+class Choice(object):
+    """
+    Represents a choice statement:
+
+      choice
+          ...
+      endchoice
+
+    The following attributes are available on Choice instances. They should be
+    treated as read-only, and some are implemented through @property magic (but
+    are still efficient to access due to internal caching).
+
+    Note: Prompts, help texts, and locations are stored in the Choice's
+    MenuNode(s) rather than in the Choice itself. Check the MenuNode class and
+    the Choice.nodes attribute. This organization matches the C tools.
+
+    name:
+      The name of the choice, e.g. "FOO" for 'choice FOO', or None if the
+      Choice has no name.
+
+    type:
+      The type of the choice. One of BOOL, TRISTATE, UNKNOWN. UNKNOWN is for
+      choices defined without a type where none of the contained symbols have a
+      type either (otherwise the choice inherits the type of the first symbol
+      defined with a type).
+
+      When running without modules (CONFIG_MODULES=n), TRISTATE choices
+      magically change type to BOOL. This matches the C tools, and makes sense
+      for menuconfig-like functionality.
+
+    orig_type:
+      The type as given in the Kconfig file, without any magic applied. Used
+      when printing the choice.
+
+    tri_value:
+      The tristate value (mode) of the choice. A choice can be in one of three
+      modes:
+
+        0 (n) - The choice is disabled and no symbols can be selected. For
+                visible choices, this mode is only possible for choices with
+                the 'optional' flag set (see kconfig-language.txt).
+
+        1 (m) - Any number of choice symbols can be set to m, the rest will
+                be n.
+
+        2 (y) - One symbol will be y, the rest n.
+
+      Only tristate choices can be in m mode. The visibility of the choice is
+      an upper bound on the mode, and the mode in turn is an upper bound on the
+      visibility of the choice symbols.
+
+      To change the mode, use Choice.set_value().
+
+      Implementation note:
+        The C tools internally represent choices as a type of symbol, with
+        special-casing in many code paths. This is why there is a lot of
+        similarity to Symbol. The value (mode) of a choice is really just a
+        normal symbol value, and an implicit reverse dependency forces its
+        lower bound to m for visible non-optional choices (the reverse
+        dependency is 'm && <visibility>').
+
+        Symbols within choices get the choice propagated as a dependency to
+        their properties. This turns the mode of the choice into an upper bound
+        on e.g. the visibility of choice symbols, and explains the gotcha
+        related to printing choice symbols mentioned in the module docstring.
+
+        Kconfiglib uses a separate Choice class only because it makes the code
+        and interface less confusing (especially in a user-facing interface).
+        Corresponding attributes have the same name in the Symbol and Choice
+        classes, for consistency and compatibility.
+
+    str_value:
+      Like choice.tri_value, but gives the value as one of the strings
+      "n", "m", or "y"
+
+    user_value:
+      The value (mode) selected by the user through Choice.set_value(). Either
+      0, 1, or 2, or None if the user hasn't selected a mode. See
+      Symbol.user_value.
+
+      WARNING: Do not assign directly to this. It will break things. Use
+      Choice.set_value() instead.
+
+    assignable:
+      See the symbol class documentation. Gives the assignable values (modes).
+
+    selection:
+      The Symbol instance of the currently selected symbol. None if the Choice
+      is not in y mode or has no selected symbol (due to unsatisfied
+      dependencies on choice symbols).
+
+      WARNING: Do not assign directly to this. It will break things. Call
+      sym.set_value(2) on the choice symbol you want to select instead.
+
+    user_selection:
+      The symbol selected by the user (by setting it to y). Ignored if the
+      choice is not in y mode, but still remembered so that the choice "snaps
+      back" to the user selection if the mode is changed back to y. This might
+      differ from 'selection' due to unsatisfied dependencies.
+
+      WARNING: Do not assign directly to this. It will break things. Call
+      sym.set_value(2) on the choice symbol to be selected instead.
+
+    visibility:
+      See the Symbol class documentation. Acts on the value (mode).
+
+    name_and_loc:
+      Holds a string like
+
+        "<choice MY_CHOICE> (defined at foo/Kconfig:12)"
+
+      , giving the name of the choice and its definition location(s). If the
+      choice has no name (isn't defined with 'choice MY_CHOICE'), then it will
+      be shown as "<choice>" before the list of locations (always a single one
+      in that case).
+
+    syms:
+      List of symbols contained in the choice.
+
+      Obscure gotcha: If a symbol depends on the previous symbol within a
+      choice so that an implicit menu is created, it won't be a choice symbol,
+      and won't be included in 'syms'.
+
+    nodes:
+      A list of MenuNodes for this choice. In practice, the list will probably
+      always contain a single MenuNode, but it is possible to give a choice a
+      name and define it in multiple locations.
+
+    defaults:
+      List of (symbol, cond) tuples for the choice's 'defaults' properties. For
+      example, 'default A if B && C' is represented as (A, (AND, B, C)). If
+      there is no condition, 'cond' is self.kconfig.y.
+
+      Note that 'depends on' and parent dependencies are propagated to
+      'default' conditions.
+
+    orig_defaults:
+      See the corresponding attribute on the MenuNode class.
+
+    direct_dep:
+      See Symbol.direct_dep.
+
+    referenced:
+      A set() with all symbols referenced in the properties and property
+      conditions of the choice.
+
+      Also includes dependencies from surrounding menus and ifs, because those
+      get propagated to the choice (see the 'Intro to symbol values' section in
+      the module docstring).
+
+    is_optional:
+      True if the choice has the 'optional' flag set on it and can be in
+      n mode.
+
+    kconfig:
+      The Kconfig instance this choice is from.

+class MenuNode(object):
+    """
+    Represents a menu node in the configuration. This corresponds to an entry
+    in e.g. the 'make menuconfig' interface, though non-visible choices, menus,
+    and comments also get menu nodes. If a symbol or choice is defined in
+    multiple locations, it gets one menu node for each location.
+
+    The top-level menu node, corresponding to the implicit top-level menu, is
+    available in Kconfig.top_node.
+
+    The menu nodes for a Symbol or Choice can be found in the
+    Symbol/Choice.nodes attribute. Menus and comments are represented as plain
+    menu nodes, with their text stored in the prompt attribute (prompt[0]).
+    This mirrors the C implementation.
+
+    The following attributes are available on MenuNode instances. They should
+    be viewed as read-only.
+
+    item:
+      Either a Symbol, a Choice, or one of the constants MENU and COMMENT.
+      Menus and comments are represented as plain menu nodes. Ifs are collapsed
+      (matching the C implementation) and do not appear in the final menu tree.
+
+    next:
+      The following menu node. None if there is no following node.
+
+    list:
+      The first child menu node. None if there are no children.
+
+      Choices and menus naturally have children, but Symbols can also have
+      children because of menus created automatically from dependencies (see
+      kconfig-language.txt).
+
+    parent:
+      The parent menu node. None if there is no parent.
+
+    prompt:
+      A (string, cond) tuple with the prompt for the menu node and its
+      conditional expression (which is self.kconfig.y if there is no
+      condition). None if there is no prompt.
+
+      For symbols and choices, the prompt is stored in the MenuNode rather than
+      the Symbol or Choice instance. For menus and comments, the prompt holds
+      the text.
+
+    defaults:
+      The 'default' properties for this particular menu node. See
+      symbol.defaults.
+
+      When evaluating defaults, you should use Symbol/Choice.defaults instead,
+      as it include properties from all menu nodes (a symbol/choice can have
+      multiple definition locations/menu nodes). MenuNode.defaults is meant for
+      documentation generation.
+
+    selects:
+      Like MenuNode.defaults, for selects.
+
+    implies:
+      Like MenuNode.defaults, for implies.
+
+    ranges:
+      Like MenuNode.defaults, for ranges.
+
+    orig_prompt:
+    orig_defaults:
+    orig_selects:
+    orig_implies:
+    orig_ranges:
+      These work the like the corresponding attributes without orig_*, but omit
+      any dependencies propagated from 'depends on' and surrounding 'if's (the
+      direct dependencies, stored in MenuNode.dep).
+
+      One use for this is generating less cluttered documentation, by only
+      showing the direct dependencies in one place.
+
+    help:
+      The help text for the menu node for Symbols and Choices. None if there is
+      no help text. Always stored in the node rather than the Symbol or Choice.
+      It is possible to have a separate help text at each location if a symbol
+      is defined in multiple locations.
+
+      Trailing whitespace (including a final newline) is stripped from the help
+      text. This was not the case before Kconfiglib 10.21.0, where the format
+      was undocumented.
+
+    dep:
+      The direct ('depends on') dependencies for the menu node, or
+      self.kconfig.y if there are no direct dependencies.
+
+      This attribute includes any dependencies from surrounding menus and ifs.
+      Those get propagated to the direct dependencies, and the resulting direct
+      dependencies in turn get propagated to the conditions of all properties.
+
+      If a symbol or choice is defined in multiple locations, only the
+      properties defined at a particular location get the corresponding
+      MenuNode.dep dependencies propagated to them.
+
+    visibility:
+      The 'visible if' dependencies for the menu node (which must represent a
+      menu), or self.kconfig.y if there are no 'visible if' dependencies.
+      'visible if' dependencies are recursively propagated to the prompts of
+      symbols and choices within the menu.
+
+    referenced:
+      A set() with all symbols and choices referenced in the properties and
+      property conditions of the menu node.
+
+      Also includes dependencies inherited from surrounding menus and ifs.
+      Choices appear in the dependencies of choice symbols.
+
+    is_menuconfig:
+      Set to True if the children of the menu node should be displayed in a
+      separate menu. This is the case for the following items:
+
+        - Menus (node.item == MENU)
+
+        - Choices
+
+        - Symbols defined with the 'menuconfig' keyword. The children come from
+          implicitly created submenus, and should be displayed in a separate
+          menu rather than being indented.
+
+      'is_menuconfig' is just a hint on how to display the menu node. It's
+      ignored internally by Kconfiglib, except when printing symbols.
+
+    filename/linenr:
+      The location where the menu node appears. The filename is relative to
+      $srctree (or to the current directory if $srctree isn't set), except
+      absolute paths are used for paths outside $srctree.
+
+    include_path:
+      A tuple of (filename, linenr) tuples, giving the locations of the
+      'source' statements via which the Kconfig file containing this menu node
+      was included. The first element is the location of the 'source' statement
+      in the top-level Kconfig file passed to Kconfig.__init__(), etc.
+
+      Note that the Kconfig file of the menu node itself isn't included. Check
+      'filename' and 'linenr' for that.
+
+    kconfig:
+      The Kconfig instance the menu node is from.

+Overview
+========
+
+A curses-based Python 2/3 menuconfig implementation. The interface should feel
+familiar to people used to mconf ('make menuconfig').
+
+Supports the same keys as mconf, and also supports a set of keybindings
+inspired by Vi:
+
+  J/K     : Down/Up
+  L       : Enter menu/Toggle item
+  H       : Leave menu
+  Ctrl-D/U: Page Down/Page Up
+  G/End   : Jump to end of list
+  g/Home  : Jump to beginning of list
+
+[Space] toggles values if possible, and enters menus otherwise. [Enter] works
+the other way around.
+
+The mconf feature where pressing a key jumps to a menu entry with that
+character in it in the current menu isn't supported. A jump-to feature for
+jumping directly to any symbol (including invisible symbols), choice, menu or
+comment (as in a Kconfig 'comment "Foo"') is available instead.
+
+A few different modes are available:
+
+  F: Toggle show-help mode, which shows the help text of the currently selected
+  item in the window at the bottom of the menu display. This is handy when
+  browsing through options.
+
+  C: Toggle show-name mode, which shows the symbol name before each symbol menu
+  entry
+
+  A: Toggle show-all mode, which shows all items, including currently invisible
+  items and items that lack a prompt. Invisible items are drawn in a different
+  style to make them stand out.
+
+
+Running
+=======
+
+menuconfig.py can be run either as a standalone executable or by calling the
+menuconfig() function with an existing Kconfig instance. The second option is a
+bit inflexible in that it will still load and save .config, etc.
+
+When run in standalone mode, the top-level Kconfig file to load can be passed
+as a command-line argument. With no argument, it defaults to "Kconfig".
+
+The KCONFIG_CONFIG environment variable specifies the .config file to load (if
+it exists) and save. If KCONFIG_CONFIG is unset, ".config" is used.
+
+When overwriting a configuration file, the old version is saved to
+<filename>.old (e.g. .config.old).
+
+$srctree is supported through Kconfiglib.
+
+
+Color schemes
+=============
+
+It is possible to customize the color scheme by setting the MENUCONFIG_STYLE
+environment variable. For example, setting it to 'aquatic' will enable an
+alternative, less yellow, more 'make menuconfig'-like color scheme, contributed
+by Mitja Horvat (pinkfluid).
+
+This is the current list of built-in styles:
+    - default       classic Kconfiglib theme with a yellow accent
+    - monochrome    colorless theme (uses only bold and standout) attributes,
+                    this style is used if the terminal doesn't support colors
+    - aquatic       blue-tinted style loosely resembling the lxdialog theme
+
+It is possible to customize the current style by changing colors of UI
+elements on the screen. This is the list of elements that can be stylized:
+
+    - path          Top row in the main display, with the menu path
+    - separator     Separator lines between windows. Also used for the top line
+                    in the symbol information display.
+    - list          List of items, e.g. the main display
+    - selection     Style for the selected item
+    - inv-list      Like list, but for invisible items. Used in show-all mode.
+    - inv-selection Like selection, but for invisible items. Used in show-all
+                    mode.
+    - help          Help text windows at the bottom of various fullscreen
+                    dialogs
+    - show-help     Window showing the help text in show-help mode
+    - frame         Frame around dialog boxes
+    - body          Body of dialog boxes
+    - edit          Edit box in pop-up dialogs
+    - jump-edit     Edit box in jump-to dialog
+    - text          Symbol information text
+
+The color definition is a comma separated list of attributes:
+
+    - fg:COLOR      Set the foreground/background colors. COLOR can be one of
+      * or *        the basic 16 colors (black, red, green, yellow, blue,
+    - bg:COLOR      magenta, cyan, white and brighter versions, for example,
+                    brightred). On terminals that support more than 8 colors,
+                    you can also directly put in a color number, e.g. fg:123
+                    (hexadecimal and octal constants are accepted as well).
+                    Colors outside the range -1..curses.COLORS-1 (which is
+                    terminal-dependent) are ignored (with a warning). The COLOR
+                    can be also specified using a RGB value in the HTML
+                    notation, for example #RRGGBB. If the terminal supports
+                    color changing, the color is rendered accurately.
+                    Otherwise, the visually nearest color is used.
+
+                    If the background or foreground color of an element is not
+                    specified, it defaults to -1, representing the default
+                    terminal foreground or background color.
+
+                    Note: On some terminals a bright version of the color
+                    implies bold.
+    - bold          Use bold text
+    - underline     Use underline text
+    - standout      Standout text attribute (reverse color)
+
+More often than not, some UI elements share the same color definition. In such
+cases the right value may specify an UI element from which the color definition
+will be copied. For example, "separator=help" will apply the current color
+definition for "help" to "separator".
+
+A keyword without the '=' is assumed to be a style template. The template name
+is looked up in the built-in styles list and the style definition is expanded
+in-place. With this, built-in styles can be used as basis for new styles.
+
+For example, take the aquatic theme and give it a red selection bar:
+
+MENUCONFIG_STYLE="aquatic selection=fg:white,bg:red"
+
+If there's an error in the style definition or if a missing style is assigned
+to, the assignment will be ignored, along with a warning being printed on
+stderr.
+
+The 'default' theme is always implicitly parsed first, so the following two
+settings have the same effect:
+
+    MENUCONFIG_STYLE="selection=fg:white,bg:red"
+    MENUCONFIG_STYLE="default selection=fg:white,bg:red"
+
+If the terminal doesn't support colors, the 'monochrome' theme is used, and
+MENUCONFIG_STYLE is ignored. The assumption is that the environment is broken
+somehow, and that the important thing is to get something usable.
+
+
+Other features
+==============
+
+  - Seamless terminal resizing
+
+  - No dependencies on *nix, as the 'curses' module is in the Python standard
+    library
+
+  - Unicode text entry
+
+  - Improved information screen compared to mconf:
+
+      * Expressions are split up by their top-level &&/|| operands to improve
+        readability
+
+      * Undefined symbols in expressions are pointed out
+
+      * Menus and comments have information displays
+
+      * Kconfig definitions are printed
+
+      * The include path is shown, listing the locations of the 'source'
+        statements that included the Kconfig file of the symbol (or other
+        item)
+
+
+Limitations
+===========
+
+Doesn't work out of the box on Windows, but can be made to work with
+
+    pip install windows-curses
+
+See the https://github.com/zephyrproject-rtos/windows-curses repository.

+
+  1. Loads existing .config
+  2. Prompts for the value of all modifiable symbols/choices that
+     aren't already set in the .config
+  3. Writes an updated .config
+
+The default input/output filename is '.config'. A different filename can be
+passed in the KCONFIG_CONFIG environment variable.
+
+When overwriting a configuration file, the old version is saved to
+<filename>.old (e.g. .config.old).
+
+Entering '?' displays the help text of the symbol/choice, if any.
+
+Unlike 'make oldconfig', this script doesn't print menu titles and comments,
+but gives Kconfig definition locations. Printing menus and comments would be
+pretty easy to add: Look at the parents of each item, and print all menu
+prompts and comments unless they have already been printed (assuming you want
+to skip "irrelevant" menus).
