# cmpVERSION - compare the current Perl source tree and a given tag
# for modules that have identical version numbers but different contents.
#
# with -d option, output the diffs too
# with -x option, exclude files from modules where blead is not upstream
#
# (after all, there are tools like core-cpan-diff that can already deal with
# them)

# Original by slaven@rezic.de, modified by jhi and matt.w.johnson@gmail.com.
