perl shapeobj values

[Sean Gillies]

Drew,

The authoritative Java/Perl/Python mapscript reference is found through  
the "MapScript Reference" link on the MapServer site. This links to

     http://zcologia.com/mapserver/

This is the online version of the docs that are distributed with  
MapServer under mapscript/docs. The same docs should also found on the  
new beta site, but seems to be borked right now.
