Dan's coding practice area

Description: Code to list the files & sub-directories contained within a user specified directory. For both Perl & Python, two scripts are given. One that uses each language's respective 'glob' support for listing files & directories that match a particular pattern, and one that uses simpler (/conceptually more-direct) routines provided by the two languages. Also, the Bourne shell code contains a 'for' loop even though technically this isn't necessary, but rather is just there to make the code modestly more interesting.
