May be I should object to such programs, then.

Do you realize  that a given user may  have several GNUSTEP_USER_ROOT,
and that his .profile may select automatically one or the other (along
with  different GNUSTEP_SYSTEM_ROOT and  GNUSTEP_LOCAL_ROOT) depending
on various circumstances.  The simpliest  of which may be a NFS-shared
home   directory   mounted   on   various   systems   with   different
architectures.


Please, tell me what can of action these programs would do?  

Why can't they work only on GNUSTEP_SYSTEM_ROOT and GNUSTEP_LOCAL_ROOT?

What good reason may have them to mess with one user's environment?
