I want to create Web HELP insted of CHM file:

Help texts must be in standard .html files.

I'm looking a tool which does the following:

1. Creates Table of contents .html page
2. Creates an index .html page
3. Creates full-text search page, using javascript of some other cross
browser way.

This help must work from C: drive even when internet connection is not
available.

Any idea or tool recommendation ?
