Actually, storing the .map file is recommended so new mappers can learn from and build off your work.
storing the
.map inside the pk3 file should
not be done, simply because the
.map file does not belong there, period. only include final, compiled content (to the extent possible). do
not include
.psd (Photoshop project file),
.flp (FL Studio project file),
.c/
.h (source code),
.map (*radiant source map), etc.; these files should be published separately, elsewhere, without bloating the "binary engine-cartridges" (pk3 files).
