[Gdal-dev] perldocs not being built and installed with 1.4.0?

Thanks for the information I'll take a look this weekend. Is there a
version of perldoc that works with .dox files? If not it seems that lack
of .pods could be an issue for a lot of perl programmers as perldoc is
ubiquitously used and referenced.

You may classify it as you wish but the docs are in the dox files. dox 
files are Doxygen files, doxygen is a source code documentation 
generator tool (http://www.stack.nl/~dimitri/doxygen/) which is used by 
other GDAL documentation. It can generate man pages but also HTML, 
LaTeX, etc. Doxygen does not directly support Perl but there is a Perl 
Doxygen Filter at http://www.bigsister.ch/doxygenfilter/ but to make 
life interesting, that filter is not directly usable in our case when we

have Swig generated Perl modules. For that purpose I modified 
doxygenfilter to add the capability to grab the docs for a module from 
an external file. The modified doxygenfilter is at 
http://map.hut.fi/files/doxygenfilter/ (I should perhaps advertise that 
a bit better somewhere). The HTML docs that I have generated from the 
dox are at http://map.hut.fi/doc/Geo-GDAL/html/ I haven't tried to 
generate the man pages.

I have informed the developers of doxygenfilter of my modifications.

There are no pod files anymore.

I recognise that the things are not very easy right now regarding the 
GDAL Perl docs, but at the same time I think that Doxygen is much better

than pod. If you have suggestions please let me know.
