Hi Monks,

I'm new to using modules and have a couple of questions regarding the following code. Note that I've included the main script named power.cgi and the module named Test.pm. 
#### Begin main script power.cgi
#!/usr/local/bin/perl
use strict;

use CGI qw(:standard);
#use lib '/httpd/cgi-bin/module';
use lib '.';
#use Test;
#use Test qw(&power);
use Test qw($hello_away &power);

my $hello_here = 'hello world from here';

# Call power in Test.pm
my $value = power(4);

print header,
   start_html('Using Module'),
   "<p>$hello_here</p>",
   "<p>$hello_away</p>",
   "$value",
   end_html,
;
#### End of main script

#### Begin module Test.pm
package Test;
use strict;
use base 'Exporter';
our @EXPORT = qw($hello_away);
our @EXPORT_OK = qw(&power);

our $hello_away = 'hello world from away';

sub power {
 my $var = shift;
 $var *= $var;
 return $var;
}
1;
#### End module

My questions are:

1) What is the difference between specifying use lib '/httpd/cgi-bin/module'; and use lib '.';?

2) It seems I have to have either two use statements use Test; and use Test qw(&power); or just this one use Test qw($hello_away &power);. Which is the preferred method?

3) How can the code be improved?

Thanks in anticpation =)
