+Saves a minimal configuration file that only lists symbols that differ in value
+from their defaults. Loading such a configuration file is equivalent to loading
+the "full" configuration file.
+
+Minimal configuration files are handy to start from when editing configuration
+files by hand.
+
+The default input configuration file is '.config'. A different input filename
+can be passed in the KCONFIG_CONFIG environment variable.
+
+Note: Minimal configurations can also be generated from within the menuconfig
+interface.
