# usage: maketarball [-drh] REVISH
#
# Creates a tarball of the repository at rev REVISH.

# If -d is passed in, then it adds the date to the directory name.
# 
# If -r is passed in, then it does some additional things required
# for a release-ready tarball.
#
# If -h is passed in, shows help and exits.
#
# Examples:
#
#    ./maketarball v0.0.2
#    ./maketarball -d master
#    ./maketarball -r v0.0.2
