+ been checked out.
+ --gnulib-srcdir=DIRNAME
+ specify a local directory where gnulib sources reside.
+ Use this if you already have the gnulib sources on your
+ machine, and don't want to waste your bandwidth
+ downloading them again. Defaults to \$GNULIB_SRCDIR.
+ --skip-git do not fetch files from remote repositories
+ --skip-po do not download po files.
+ -v, --verbose verbosely report processing
+ --version print version information and exit
+ -W, --warnings=CATEGORY
+ report the warnings falling in CATEGORY [all]
+ -h, --help print short or long help message and exit
