I'm not sure about using "group" instead of "source", for various reasons...

1) "source" seems more directly intuitive than "group". Seeing as it maps
directly to the intended use in "<target-rule> <target-name> : <**sources**>
: <requirements> ;"

2) I don't see a problem in using "source" with main targets as you point
out. This seems perfectly obvious to me also:

lib my_i18_lib : source.cpp ;
source os-abstraction : win.cpp my_i18_lib : <os>NT ;

3) We might want to use "group" for the categorization of targets that is
needed for the stage rule. For example:

lib some-lib : source.cpp : <group>one ;
lib another-lib : source2.cpp : <group>two ;
stage release : : <group>two ;

Don't hold me to that grammar ;-) It looks kinda of klunky, but using
"group" for this make more sense to me than using it for grouping sources.
