Yeap.. Such think exist, some time ago i converted mIRC Help from .hlp to .chm what in fact mean i converted one big .rtf to lots of small .html.. The .chm file can be easily decompiled, so these html's was nevere somthink private.. Heh.. Take it..
I figured out how can i run xCHM under windows(that first time when i ussing cygwin).. But xCHM seem do not whant to show Index Tab when Table of Contents is not avaible.. So i compile mirc.chm with TOC.. And it seem to work fine..
