[mapserver-users] symbols indexed by an attribute

[Pushkar Pradhan]

Thanks Steve,
I am now trying to built mapscript with perl, but there doesn't seem to be
any documentation on that. Can anyone point me if there is docum.
available on this, otherwise I will try to use php/mapscript?
I welcome suggestions and your experience from everybody about perl vs.
php with mapscript.
