Good morning and welcome.
EQEmu is an open source project that keeps a (usually) updated copy of its source code on SourceForge. The project is here:
http://sourceforge.net/projects/eqemulator/
The project is written in C++ and uses MySQL for a database. The official builds are for Windows, compiled with MS Visual Studio, but since several server ops use Linux you need to refrain from using any "Winblows-only
" functions or datatypes that could cause portability problems.
For servers that are into quests, the code includes hooks for Perl scripting for the quests. To take advantage of it, you must have Perl and IO::Scalar installed (one of EQEmu's Howto's covers this, and ProjectEQ has a quest tutorial here:
