# xchm xCHM is a cross-platform GUI front-end to chmlib, with borrowed bits from Pabs' chmdeco project. Originally written for UNIX systems (Linux, *BSD, Solaris), xCHM has been since ported to Mac OS X and Windows. xCHM can show the content tree if one is available, print pages, change font face and size, remember bookmarks, display a searchable index, and search for words in the current page and the whole book.
