[Gdal-dev] swig/perl

[Kevin Ruland]

Congratulations Ari!

Perl should be able to do the tostring argin pretty easily since it
takes any object and "string-ifies" it.

IF_FALSE_RETURN_NONE should also be pretty easy since Perl has a very
nice sense of none.

Send me the code and we'll put it in CVS.
