what's the best make.conf for current? How does developer dist translates into make.conf

Hi,

When I install Freebsd from cd with Sysinstall I selected Developer as 
distribution. After cvsup-ping I went into make.conf and tried to determine 
what I want to build with buildworld. 

I want to buildworld with the same settings chosen in sysinstall, however I am 
unable to find how developer translates into a make.conf.

Reviewing man sysinstall and google does not shed much light on the matter. 
Anyone to clarify this or know where to find?

Rgds,

Patrick
