Another script that is more for reading and learning than running.
This example highlights REBOL's power for writing short,
succinct solutions.
This script really does need to be read, to be appreciated.
Another simple one, Just DO it.
From a REBOL console session,
>>do %beersong.r
or
>>do http://www.rebol.org/cgi-bin/cgiwrap/rebol/download-a-script.r?script-name=beersong.r
and the machine will print out the words to a famous song.
