Modifying environment variables

| script from the users' .cshrc file (I should've
| mentioned that they are invariably using csh or
| tcsh).

Right, it does no good to modify the environment.  You have to
write the value to output, and read it into PATH from the shell -
like  % setenv PATH `fudgepath`
