Trying to write my first pm file.

[Timothy Fletcher via modules]

Hi,
Trying to write my first pm file for cpan.
And well, reading the example suggest to look at;
http://search.cpan.org/~muir/Text-Tabs%2BWrap-2013.0523/lib.old/Text/Tabs.pm

SYNOPSIS 
  use Text::Tabs;

  $tabstop = 4;  # default = 8
  @lines_without_tabs = expand(@lines_with_tabs);
  @lines_with_tabs = unexpand(@lines_without_tabs);

they don't match the source.

=head1 SYNOPSIS

        use File::Copy;

        copy("sourcefile","destinationfile") or die "Copy failed: $!";
        copy("Copy.pm",\*STDOUT);
        move("/dev1/sourcefile","/dev2/destinationfile");

        use File::Copy "cp";

        $n = FileHandle->new("/a/file","r");
        cp($n,"x");

Other than your example pages, Oreilly book of swimming of perl( flipping pages 
for ever ) is there step by step process example, for why and what?
