### USAGE ###
#
#    tag [-u username] [-p password] repository version [last-version]
#
# Typing in -u but not -p will prompt you for a password.  
# Priving a last-version argument will create a diff file between the new version and last-version tag.  
# repository is automatically appended to REPOROOT.
