I'd just like to interject for a moment. What you’re referring to as Zandronum, is in fact, ZDoom/Zandronum, or as I’ve recently taken to calling it, ZDoom plus Zandronum. Zandronum is not a source port unto itself, but rather another free component of a fully functioning ZDoom system made useful by the ZDoom corelibs, rewritten source files and vital system components comprising a full source port as defined by Romero.
Many doomers run a modified version of the ZDoom system every day, without realizing it. Through a peculiar turn of events, the version of ZDoom which is widely used for multiplayer is often called “Zandronum”, and many of its users are not aware that it is basically the ZDoom system, developed by Graf Zahl. There really is a Zandronum, and these people are using it, but it is just a part of the port they use.
Zandronum is the parser: the program in the system that reads wads and pk3s. The parser is an essential part of an source port, but useless by itself; it can only function in the context of a complete source port. Zandronum is normally used in combination with the underlying ZDoom source: the whole system is basically ZDoom with Zandronum added, or ZDoom/Zandronum. All the so-called “Zandronum” ports are really modifications of ZDoom/Zandronum.
