Usage: $program [-z|--zero] [-a|--add] [-g|--clean-git] [-s|--set NUM]
[-t|--test] [-f|--force] DIR or APKBUILD...
Options:
-z, --zero Set pkgrel to 0
-a, --add Add 1 to current pkgrel
-g, --clean-git Only operate on APKBUILDs with clean git status (implies
--add)
-s, --set NUM Set pkgrel to NUM
-t, --test Only verify that files have a valid pkgrel
-f, --force Operate on files without a valid pkgrel
-h, --help Show this help
