Environment variables

[Louis M. McDonald]

I would like to have a program permanently set environment variables.
I guess I thought putenv would do it, but seem to be wrong. After the 
program completes, the enviroment variables are the same (if already exist)
or do not exist (if new).

Basically, I would like to have something that does not require me to
have a user `source' a file to get the environment variables I want defined
for his/her session.
