Basically, there are some scripts that currently need to be sourced to
get all the proper environment variables. In the scripts I set up for a
related product, I not only source the environment scripts, I update
them because I'm merging 2 products. Setting up the path in these
sourced files is trivial. I think at this point, my coworker is planning
to do that.
