The only thing I can think of is to set the PERL5OPT variable, as defined in perldoc perlrun: export PERL5OPT=-MMyPackage Now MyPackage will be use'd whenever you invoke perl, subject to the caveats in perldoc perlrun. There may be another way; I'm not sure. I think it's safest to just put the "use MyPackage;" in every script that needs it. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
