I want to have only one copy of Formmail(my example) program sit in one place and user can access it indirectly(fill in form and send mail thr it). this way, if formmail has new update come out, i can make a change very quickly.
something like this

i have formmail.pm which is one big

sub run { everything else here }
[download]

then each user cgi-bin dir has mailer.cgi :

use libs '/where/formmail.pm/is';
run;
[download]

but i am stuck. i tried the above approace, it loads up the form, and once the form submitted, it try to locate formmail.cgi in the same dir where mailer is. i don't know how exactly i should make it works as i expect. i need idea/concept..

There are probably other ways(better) to do it, i would love to hear it too.

TIA,
James.
