IStorage file format.

[Psyon]

I am interested in making an HTMLHelp (.CHM) viewer for Linux.  I am
told the files are actually IStorage files.  I have been scouring the
internet looking for information about this format with no avail.  I
have also been looking over the WINE implementation, to see if that
would shed some light on the format, but the code dives into a bunch of
cryptic functions that I cant seem to follow.  Is there any documents
describing the format of these files?   even just a brief description
would be nice at this moment.

If you have any information please replay directly to me at

Thanks in advance
