I did not understand completely what you wrote and assumed that you  
were still referring to the usual files a shell interpreter is reading  
when it is started.

Mac OS X allows to set up some so-called "Startup Items"...

That's indeed not possible inside ~/.MacOSX/environment.plist. It's  
just a simple text, or, better: XML file. Inside it no substitution  
happens. With GNU Emacs or some other editor it's really not that  
complicated to substitute variable names with the contents they stand  
for.

OTOH, a shell should be able resolve a setting like "$SW_HOME/groovy/ 
current" when "$SW_HOME" is given. Proof:

	ls -l $SW_HOME/groovy/current
