usage: $0 GNULIB-DIR
$0 synchronizes mailutils library with gnulib.
GNULIB-DIR is the directory where gnulib sources reside. The program
reads file gnulib.modules, populates the mailutils tree with the
necessary files from GNULIB-DIR and updates Makefile.am-s.
Options:
--verbose Display every operation
--dry-run Do not do anything, just print what would have been done
--help Display this help list
