// Using Quake2 3.17's built-in support for VWep:

// You can figure out how to do 3.17 VWep by reading the 3.15/3.17 Q2 release
// notes and looking at the DM2 specs maintained by Uwe Girlich at
// http://www.planetquake.com/demospecs/dm2/dm2.html

// This code is obviously not the most efficient and there's some
// double maintenance, but it's the simplest way to show how things work.
// I'm assuming you have Hentai's VWep code patched into your
// mod so you already have the calls to ShowGun() in the correct places.
// If you don't have Hentai's original VWep code, get it here:
// ftp://ftp.telefragged.com/pub/vwep/vwep_src.zip

// You can easily rewrite this code to eliminate double maintenance
// and make it more much efficient, which is what I've done for L-Fire CTF.

// Thanks to NaTS and Thomas (don't know their real/last names) on the
// PlanetQuake Q2 Coding list for discussing this with me and helping to
// get it working properly.
