WinCHM is a very easy-to-use help authoring tool. Not
needing to learn too much, you can be master of creating
HTML help(CHM), Web help, PDF and Word documents. Using
WinCHM you can not only make help files with nothing, but
also convert a set of HTML files into a CHM file. WinCHM
combines a WYSIWYG (What You See Is What You Get) html
editor and a content tree-view in one window. You can
easily navigate the Table of Contents and insert or edit
help topics without much fuss.
