Help+Manual (AKA: Help & Manual, Help And Manual) is currently the most powerful WYSIWYG help files creating tool (from Austria) on the market. Due to the use of pure XML format of visual editor, there is no difference between Help+Manual's usage and the use of many common word processors. It can be used to make very professional and beautiful product manuals, HTML pages, RTF, and help files in PDF format.

CHM (Microsoft Compiled HTML Help) is a convenient document format suitable for quick browse and query, which is very common in all kinds of help documentations. In particular, its production process does not become complicated because of its powerful features; on the contrary, that's as simple as reading it. So, all we need is just a professional CHM making tool.

htm2chm is a very practical CHM file (Microsoft Compiled HTML Help) creator, compiler, editor and decompiler I found a few years ago when searched "convert flash into CHM" in Google. At that time, I wanted to pack a flash file along with its related documents (HTML, TXT, ZIP, etc) as a CHM format e-book, so that I can take it anywhere.
