MemGuard is a MungWall/WipeOut/MuGuardianAngel-like program that munges
memory and watches illegal memory allocations and releases. As I'm too
lazy to write a proper documentation;), you should be familiar with one
of the programs mentioned above. MemGuard is written for use with Amiga
OS4.

The archive was packed on a Linux machine, the 'e' protection bit of the
executeable could be missing!
