=item -D=lib

=item -Dlib

=item --no-dev-lib

Add paths to @INC before loading ANYTHING. This is what you use if you are developing yath or yath plugins to make sure the yath script finds the local code instead of the installed versions of the same code. You can provide an argument (-Dfoo) to provide a custom path, or you can just use -D without and arg to add lib, blib/lib and blib/arch.

=item --persist-file ARG

=item --pfile ARG

=item --pfile=ARG

=item --no-persist-file

Where to find the persistence file. The default is /{system-tempdir}/project-yath-persist.json. If no project is specified then it will fall back to the current directory.
