From: paveza@ix.netcom.com
Due to the number of responses I received for this code, I am merely
posting it to the list instead of replying to individual requests. I have
used some of the code or at least the ideas for some code from this mailing
list, so I feel it is only fair to give back :). This code is provided as
is, no warranty is made. Please send an email to
staffa@apache.wildstar.net or paveza@ix.netcom.com if you use this code in
your mud. Other than that, please make some kind of notation (via comments
is fine) in your source code indicating that the snippet was created by
Joseph Keslin (aka Tyric). He is the co-IMP of Last Aerie and has granted
permission to distribute this code.
Note that some of the fields the whowas is looking for are ones that we
have added on (such as hostname). I leave it as an exercise of the reader
to perform the task of adding them to the pfiles. If help is needed, just
email me and I will see what I can do.
Enjoy.
