+ -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
