In my ongoing quest to find a good tool to create our help files for a web application we are building, I stumbled over the following tool: chmProcessor
“chmProcessor is a tool that allows generating a help project and a compiled HTML help (CHM file) from a MS Word or HTML 4 file. If the file is a word document, the section titles must use the “Title 1”, “Title 2”, etc styles that offers by default Word. If the file is a HTML 4 file, the titles must use the <H1>, <H2>, etc. tags.
From this original file, each section of the document is split to different HTML files. Each of these files will be a topic page at the help. From the original document, you can generate:
· A Microsoft Help Workshop project.
· A compiled HTML help (CHM file).
· A web site like this.
· An Adobe PDF file.
· A Microsoft XPS file.
· A Java Help JAR file.”
