====== Introduction ======
This page contains information about a plugin developed for GeSHi to support Prolog syntax highlighting.

This simple idea came to mind of Grzegorz J. Nalepa and Igor Wojnicki who were also the first testers.

The implementation was carried out in 2007 by a student Paweł Kupka. 

Grzegorz J. Nalepa <gjn@agh.edu.pl> supervised the implementation.

====== Future work ======

The plugin has been submitted to GeSHi on 29/02/2008.

The plugin is being extended to support [[http://www.logtalk.org|Logtalk]], see the [[http://forums.logtalk.org/viewtopic.php?f=18&t=12|forum post]].
