Yes, you're right that changing _homeextra_ involves editing the C++
code, and what you describe sounds about right.

An easier alternative is to customise the home.dm macrofile instead of
the C++ code. Doing this allows you to customise the home page to show
whatever you want -- but it won't be as dynamic. For example, Greenstone
CD-ROMs have a customised home page with the 11 documented example
collections listed with an icon and a description. To achieve this, the
_content_ macro in the home.dm was changed to include a bunch of HTML
for the table containing the icons and descriptions. You can see the
customised home.dm file here:
http://www.cs.waikato.ac.nz/~mdewsnip/greenstone/temp/home.dm.

Of course, if you do it this way your home page becomes more static, and
you'll have to update it when your collections change. But it's a lot
simpler, and you don't have to touch the code.

If you'd rather go the C++ route, let me know and I'll look into it further.

Regards,

Michael
