PerlMUD is written in Perl 5.0 and is highly compatible with the well-known TinyMUD command set, which provides a friendly interface to your online environment. PerlMUD is inexpensive shareware, and complete Perl source code is included. Administrators can easily extend the PerlMUD system by writing additional Perl code. Free Trial/$25
