# urlenc converts a string or raw data to a url-encoded string 
# (url encoding is really just fancy hex encoding)
#
# Usage: urlenc [options] <data | blank for stdin>
#     -h, --help                       Show this message
#     -v, --version                    Show version and exit
#     -f, --file FILENAME              Input from FILENAME
#     -p, --[no-]plus                  Convert spaces to '+' (default is false)
