+# Implements a simple configuration interface on top of Kconfiglib to
+# demonstrate concepts for building a menuconfig-like. Emulates how the
+# standard menuconfig prints menu entries.
+#
+# Always displays the entire Kconfig tree to keep things as simple as possible
+# (all symbols, choices, menus, and comments).
+#
+# Usage:
+#
+#   $ python(3) Kconfiglib/examples/menuconfig.py <Kconfig file>
+#
+# A sample Kconfig is available in Kconfiglib/examples/Kmenuconfig.
+#
+# Here's a notation guide. The notation matches the one used by menuconfig
+# (scripts/kconfig/mconf):
+#
+#   [ ] prompt      - Bool
+#   < > prompt      - Tristate
+#   {M} prompt      - Tristate selected to m. Can only be set to m or y.
+#   -*- prompt      - Bool/tristate selected to y, pinning it
+#   -M- prompt      - Tristate selected to m that also has m visibility,
+#                     pinning it to m
+#   (foo) prompt    - String/int/hex symbol with value "foo"
+#   --> prompt      - The selected symbol in a choice in y mode. This
+#                     syntax is unique to this example.
+#
+# When modules are disabled, the .type attribute of TRISTATE symbols and
+# choices automatically changes to BOOL. This trick is used by the C
+# implementation as well, and gives the expected behavior without having to do
+# anything extra here. The original type is available in .orig_type if needed.
+#
+# The Kconfiglib/examples/Kmenuconfig example uses named choices to be able to
+# refer to choices by name. Named choices are supported in the C tools too, but
+# I don't think I've ever seen them used in the wild.

+Generates a header file with #defines from the configuration, matching the
+format of include/generated/autoconf.h in the Linux kernel.
+
+Optionally, also writes the configuration output as a .config file. See
+--config-out.
+
+The --sync-deps, --file-list, and --env-list options generate information that
+can be used to avoid needless rebuilds/reconfigurations.
+
+Before writing a header or configuration file, Kconfiglib compares the old
+contents of the file against the new contents. If there's no change, the write
+is skipped. This avoids updating file metadata like the modification time, and
+might save work depending on your build setup.
+
+By default, the configuration is generated from '.config'. A different
+configuration file can be passed in the KCONFIG_CONFIG environment variable.
+
+A custom header string can be inserted at the beginning of generated
+configuration and header files by setting the KCONFIG_CONFIG_HEADER and
+KCONFIG_AUTOHEADER_HEADER environment variables, respectively (this also works
+for other scripts). The string is not automatically made a comment (this is by
+design, to allow anything to be added), and no trailing newline is added, so
+add '/* */', '#', and newlines as appropriate.
+
+See https://www.gnu.org/software/make/manual/make.html#Multi_002dLine for a
+handy way to define multi-line variables in makefiles, for use with custom

+  1. Loads existing .config

+     aren't already set in the .config
+  3. Writes an updated .config
+
+The default input/output filename is '.config'. A different filename can be

+
+When overwriting a configuration file, the old version is saved to

+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
