When people say "FLRP Scripting" what exactly do they mean?

[Biowulf]

I would start with C. Ever tried programming in C, C#, C++ or Lua sniper. If you start with C++ you're brilliant. I prefer sticking with C for the beginners and when you're experienced with it, move on to C++.

[Edit]
And no, there is a difference between Lua, and the Gmod Lua. I don't see they have so much in common though. All different commands etc.
