Why use pod??
POD is "plain old documentation".
It's a simple language for uniform documentation.
It's very easy to use.
POD主要是用于模块
Example.pm
__END__

Template - Description goes here
=head1 SYNOPSIS

my $o = Template->new;
=head1 METHODS
=over 4
=item B<new>

Returns a blessed Template object reference.
=item B<method>
Describe the method here
=back
=head1 AUTHOR
Written by Your Name
=head1 HISTORY
Version history here.
=cut

这个还是要结合pod的源代码和最终的pod来看。
