Linkbot started out in our old IRC channel, #uacs, on freenode. The idea was simple: people post a lot of interesting links on IRC and sometimes you want to look at them again later. Linkbot collects all the links posted in the channel in a simple text file, and there is a CGI script to display them online.
I haven't used or maintained this code in years. It may not work, it may have a horrible security hole, etc. No warranty.
Linkbot is based heavily on Simple IRC Client from suckless.org. It retains the MIT/X license of SIC.
Linkbot requires a C compiler and a UNIX-like OS. That's it.
The CGI script for viewing links requires Perl and the CGI Module. That's it.
