Starting small is not too hard. Here is module Foo.pm:
package Foo;
require Exporter;
@ISA = qw|Exporter|;
@EXPORT_OK = qw|foo|;
sub foo
{
print "Hello World\n";
}
1;
And here is how it is used:
use Foo foo;
foo();
print "Goodbye\n";
Simplicity itself: we mark the routine
foo()
as exportable and import it with
use Foo foo;.
The complexity you saw comes if you want to package up your
module as a full blown library worthy of CPAN. For that you
will want to read
perlman:perlmod to see how modules work
and
perlman:perlmodlib to see how to create them. Also check
out
perlnewmod
for preparing a new module for distribution.
