Investigate Hexen II & Quake .map files
is an easy-to-use yet extremely powerful command line tool to find entities in .map files and learn from the skilled mappers (I mean those at Raven, not me!) :-)
It works for Hexen II and Quake .map files as well.
The zip file contains the exe + config file + readme file + changelog.
Please tell me
if you see anything wrong or improvable.
