p.mapper *does support* Mapserver groups defined in the map file. This required 
quite some efforts and workarounds since Mapscript has no support for groups as 
the CGI has.  

Groups are an internal feature of Mapserver for logical grouping, categories 
are an additional feature of p.mapper for thematic grouping in the TOC. Both 
can be used together, but one has to be aware of the different use cases and 
mechanisms that apply. 

Since Mapserver does not support additional levels like categories they have to 
be defined outside of Mapserver. The definition is also too complex (2-level 
array) for putting them into the ini file, therefore the definition in another 
config. You can of course define them elsewhere (eg. in a DB, XML, etc), just 
need to write everything into a session variable.
