MapScript SetSymbolSet

[Christopher Condit]

But then I'll have an extra file lying around.

The original problem was that I wanted to use the same symbol set for
every user session.  I don't know why that failed.  But now I've got it
working - I hacked mapserver so that symbols always gets inMapFile set
TRUE.  This solves my problem for now.  I guess I should add a check to
see if symbolsetname is null.  If not, then write to mapfile, otherwise
write to symbolfile.  Or I guess you should be able to have both!
Symbols in the mapfile and external symbols...

You should save the symbolset before saving the map

see
