A wxWidgets CHM document viewer
xCHM is a cross-platform GUI frontend for CHMLIB, written with wxGTK. It is able to display the topics tree, work with displayed pages history, print the current page, work with bookmarks, change fonts and fast search through all the pages of the loaded .chm document. Being indirectly dependent on GTK+, the possibility of changing GTK+ skins makes xCHM theme-friendly.
