+#  After doing a make localyesconfig, your kernel configuration may
+#  not be the most useful minimum configuration. Having a true minimum
+#  config that you can use against other configs is very useful if
+#  someone else has a config that breaks on your code. By only forcing
+#  those configurations that are truly required to boot your machine
+#  will give you less of a chance that one of your set configurations
+#  will make the bug go away. This will give you a better chance to
+#  be able to reproduce the reported bug matching the broken config.
+#
+#  Note, this does take some time, and may require you to run the
+#  test over night, or perhaps over the weekend. But it also allows
+#  you to interrupt it, and gives you the current minimum config
+#  that was found till that time.
+#
+#  Note, this test automatically assumes a BUILD_TYPE of oldconfig
+#  and its test type acts like boot.
+#  TODO: add a test version that makes the config do more than just
+#   boot, like having network access.
+#
+#  To save time, the test does not just grab any option and test
+#  it. The Kconfig files are examined to determine the dependencies
+#  of the configs. If a config is chosen that depends on another
+#  config, that config will be checked first. By checking the
+#  parents first, we can eliminate whole groups of configs that
+#  may have been enabled.
+#
+#  For example, if a USB device config is chosen and depends on CONFIG_USB,
+#  the CONFIG_USB will be tested before the device. If CONFIG_USB is
+#  found not to be needed, it, as well as all configs that depend on
+#  it, will be disabled and removed from the current min_config.
+#
+#  OUTPUT_MIN_CONFIG is the path and filename of the file that will
+#   be created from the MIN_CONFIG. If you interrupt the test, set
+#   this file as your new min config, and use it to continue the test.
+#   This file does not need to exist on start of test.
+#   This file is not created until a config is found that can be removed.
+#   If this file exists, you will be prompted if you want to use it
+#   as the min_config (overriding MIN_CONFIG) if START_MIN_CONFIG
+#   is not defined.
+#   (required field)
+#
+#  START_MIN_CONFIG is the config to use to start the test with.
+#   you can set this as the same OUTPUT_MIN_CONFIG, but if you do
+#   the OUTPUT_MIN_CONFIG file must exist.
+#   (default MIN_CONFIG)
+#
+#  IGNORE_CONFIG is used to specify a config file that has configs that
+#   you already know must be set. Configs are written here that have
+#   been tested and proved to be required. It is best to define this
+#   file if you intend on interrupting the test and running it where
+#   it left off. New configs that it finds will be written to this file
+#   and will not be tested again in later runs.
+#   (optional)
+#
+# Example:

+#  TEST_TYPE = make_min_config
+#  OUTPUT_MIN_CONFIG = /path/to/config-new-min
+#  START_MIN_CONFIG = /path/to/config-min
+#  IGNORE_CONFIG = /path/to/config-tested
