If you know a bit of perl, why not add the ada_include_path and
ada_object_path yourself ?... The script is in the /bin directory
of your GNAT distrib. But I feel there is a good reason to make these
options _explicit_. 

[...]
For use with non-GNAT sources, it doesn't harm: you gnatmake it and
if the Ada is valid, all .ali files are created, even if link fails
due to such and such import. I'm doing so to html-ize a project made
with DEC Ada.

Didn't find it in the .pl, but again it is surely too much:

 - perhaps the .ali contains already the right alternative name (-> GNAT RM)
 - for alternernative naming, it is *easy* to do. Say you have plenty of
   .ada files (some with spec+body, some with non-GNAT naming - my case).
   You type "gnatchop *.ada", and 1 second later you have all .ads and
   .adb ! Then gnatmake xxxx, you have the .ali files. Finally: perl
gnathtml ...
   and you have the Web site.

The tool works well. It would *just* be cool to customise the tool.
E.g. allow to add headers, links outside the main page, "A HREF"-ize
the URLs in strings, why not add a tag for a background image ;-) ?
I don't understand much of Perl, but who knows, with a bit of guess-work ?...

But isn't the author of gnathtml.pl reading here ?...
