[ Apologies, this should probably be going to the new pkgsrc users list,
 but I seem to have deleted the announcement message and can't remember

I'm wanting to configure rt3 with the appropriate arguments in /etc/mk.conf
for my site, but I've not come across PKG_OPTIONS_GROUP before ...
I'm familiar with using 
 PKG_OPTIONS.blah = quux -foo
but would for the following definitions for rt3:
 PKG_OPTIONS_VAR= PKG_OPTIONS.rt
 PKG_OPTIONS_REQUIRED_GROUPS= backend frontend
 PKG_OPTIONS_GROUP.backend= mysql pgsql
 PKG_OPTIONS_GROUP.frontend= modperl1 modperl2 \
 fastcgi
 PKG_SUGGESTED_OPTIONS= mysql fastcgi
 
 PKG_OPTIONS_LEGACY_OPTS= backend-mysql:mysql backend-pgsql:pgsql \
 frontend-modperl1:modperl1 \
 frontend-modperl2:modperl2 \
 frontend-fastcgi:fastcgi
would I need to do something like
 PKG_OPTIONS.rt.backend = pgsql
 PKG_OPTIONS.rt.frontend = modperl1
or something like
 PKG_OPTIONS.rt = backend:pgsql frontend:modperl1
Is there documentation on this I could look at (apart from UTSL, I guess)
Regards,
Malcolm
