Usage: $PROGNAME [options] .deb-file [log message]
$PROGNAME -o <version> -c
Increase the .deb file's version number, noting the change in the
changelog with the specified log message. You should run this
program either as root or under fakeroot.
Options:
_eousage
cat <<-_eooptions | column -s\& -t
-v ver|--new-version=ver & use this as new version number
-o old|--old-version=ver & calculate new version number based on this old one
-c|--calculate-only & only calculate (and print) the augmented version
-s str|--string=str & append this string instead of '$VERSTR' to
& calculate new version number
-k script|--hook=script & call this script before repacking
-D|--debug & call dpkg-deb in debug mode
-b|--force-bad-version & passed through to dch
-h|--help & show this output
-V|--version & show version information
