 # Used to detect missing dependencies or automagically
 # enabled dependencies which aren't explicitly enabled
 # or disabled. Using bash to have PIPESTATUS variable.

 # It does 3 builds of <target>
 # 1st to populate sstate-cache directory and sysroot
 # 2nd to rebuild each recipe with every possible
 #     dependency found in sysroot (which stays populated
 #     from 1st build
 # 3rd to rebuild each recipe only with dependencies defined
 #     in DEPENDS
 # 4th (optional) repeat build like 3rd to make sure that
 #     minimal versions of dependencies defined in DEPENDS
 #     is also enough

 Welcome to utility to detect missing or autoenabled dependencies.
 WARNING: this utility will completely remove your tmpdir (make sure
          you don't have important buildhistory or persistent dir there).
 $0 <OPTION>

 Options:
   -h, --help
         Display this help and exit.

   --tmpdir=<tmpdir>
         Specify tmpdir, will use the environment variable TMPDIR if it is not specified.
         Something like /OE/oe-core/tmp-eglibc (no / at the end).

   --targets=<targets>
         List of targets separated by space, will use the environment variable TARGETS if it is not specified.
         It will run "bitbake <targets>" to populate sysroots.
         Default value is "world".

   --recipes=<recipes>
         File with list of recipes we want to rebuild with minimal and maximal sysroot.
         Will use the environment variable RECIPES if it is not specified.
         Default value will use all packages ever recorded in buildhistory directory.

   --buildhistory=<buildhistory>
         Path to buildhistory directory, it needs to be enabled in your config,
         because it's used to detect different dependencies and to create list
         of recipes to rebuild when it's not specified.
         Will use the environment variable BUILDHISTORY if it is not specified.
         Default value is "buildhistory"

   --buildtype=<buildtype>
         There are 4 types of build:
           1: build to populate sstate-cache directory and sysroot
           2: build to rebuild each recipe with every possible dep
           3: build to rebuild each recipe with minimal dependencies
           4: build to rebuild each recipe again with minimal dependencies
           c: compare buildhistory directories from build 2 and 3
         Will use the environment variable BUILDTYPE if it is not specified.
         Default value is "1 2 3 c", order is important, type 4 is optional.
