PATCH for help-browser

[Martin Hawlisch <hawlisch roxi rz fh-mannheim de>]

Hi!

Attached you can find a patch for the GNOME help-browser (latest CVS
version from HEAD branch).
What it does is the following:
Currently in toc:ghelp only packges are listed that put a index.html file
into their subdir.
Some apps like gnumeric and gnomecal do have helpfiles but not a
index.html.
I modified toc2-ghelp.c that generates the entries to also read the
topic.dat file and extract the first helpfile name.
My extension is basically a cut and paste from toc2-ghelp.c and the
gnome-app-helper.c files.

Hope you like it.

... Or shoud we force the apps to install a index.html file?


Cheers, Martin.
