The same way it will help anywhere else. By directing one nightly build to install stuff in a different place than the other. Am I missing something obvious here about your point? Because you seem to be contradicting my original premise, without coming out and saying so. Re: command line versus environment, a quick test showed me that, for instance, mzscheme accepts -X but plt-help does not. So a "run PLT executables via script based on $PLTHOME" solution suddenly has to special case different options for each command. The nice thing about environment variables is that the same set works for every command; extra ones are ignored. --Carl _________________________________________________ For list-related administrative tasks: http://list.cs.brown.edu/mailman/listinfo/plt-dev
