Re: problems with XFree

Jehan,

As a rule of thumb, packages should *never* modify the /etc/profile
script (even if you do back it up).  This is a big no-no, as most
*nix people would tell you.  If you insist on getting into a
discussion on why this is, then so be it.  Instead, create 2 scripts
(a csh and a sh) and drop them into the /etc/profile.d/ directory. 
This way we play it safe and every one is happy.  Also, your scripts
should check to see if the path has already been set, if it has, then
don't set it again.  Remeber, the more entries in the path, the
slower Cygwin will operate.

Cheers,
Nicholas
