HelpScribble is a full-featured, easy-to-use help authoring tool for creating help files from start to finish. Create WinHelp (.hlp) files, HTML Help (.chm) files, a printed manual and online documentation (on a web site) all from the same HelpScribble project.
Write full-featured help files with the built-in editors for SHG files (hotspot bitmaps), WinHelp macros, contents tree, browse sequences, etc.
If you have previously used another help authoring tool, reuse your work by importing the HPJ+RTF files created with the other tool or by a decompiler.
Use the help files you make with HelpScribble to provide context-sensitive help with your Window applications, no matter which development tool you use. If you use Borland Delphi or C++Builder, you will like the way HelpScribble's HelpContext property editor integrates with them to make assigning Topic ID values to HelpContext properties very easy.
HelpScribble is a stand-alone tool. It does not depend on MS Word or any other third party package. It does need a help compiler that you can download for free from http://www.helpscribble.com/helpcompiler.html
