* debug.cpp *
* NB change the path and name of the debugfile in debug.h before using *
* the debug functions. To enable debug functions change the commented *
* line in the debug.f header file. Warning - debug files can get very *
* big quite quickly. I only use them for hard to finc bugs. *
* One alternative is just to call the DebugMessage function at any *
* point without using #ifdef DEBUG.... and then you'll get a smaller *
* file referencing the area you are interested in. (Or just use *
* Messageboxes for real small bugfinding.... Anyway, the functions are *
* there should they be required. Eugen Polukhin had suggested using a *
* second screen for the debug messages, with the ability to switch *
* between the two with a keypress. It looked good, but in reality it's *
* not as useful because most bugs I would use this for are fatal... *
