coldhawk has asked for the wisdom of the Perl Monks concerning the following question:

I was just thinking, what would be the best way to regonize how is the program being called. What i real mean is, that im trying to find out if it's exec directly or is another perl program using it with require, and do actions based on that. I couldn't find any portable solutions to this, maybe i was searching with wrong search words, but anyway. i would appreciate of any help you may give.

    if ($0 eq __FILE__) { print "Called directly\n"; } else { print "Loaded in a library\n"; }

    If the program knows its own name, $0 may help.

    perldoc -f caller is maybe also a good hint.
