	    use CGI qw/:standard/;

Nice slap, but wrong answer.  This doesn't do the same thing at
all, and it's not what was asked for.  More likely, the answer
should be:

	require "common.cgi";

This will read in the file, and compile its contents into the
program.  It's a run-time command, unlike "use", which happens
at compile time.  The "use" command also does some other things
that you probably don't want done if you're just trying to load
in a few of your own routines.

Note that "common.cgi" should end with:

The require command expects a return value that tells it whether
the package thinks it was loaded successfully.  This tells require
that everything was loaded OK (and a second require of the same file
will be a no-op).
