From the keyboard of jmc@eagle.inesc.pt (Miguel Casteleiro):
:I need to set some environment variables in a Perl script,
:and, at the end of the script, I need them to be exported to
:the running shell (tcsh).  So, how can I do that?

You need to write them to stdout and eval the output.

% eval `cmd`

where cmd is a perl script that outputs something like:

    setenv foo bar;  setenv alpha omega; 

etc.
