=head1 NAME

WWW::Shorten::TinyURL - Perl interface to L

=head1 SYNOPSIS

  use strict;
  use warnings;

  use WWW::Shorten::TinyURL;
  use WWW::Shorten 'TinyURL';

  my $short_url = makeashorterlink('http://www.foo.com/some/long/url');
  my $long_url  = makealongerlink($short_url);

=head1 DESCRIPTION

A Perl interface to the web site L.  The service simply maintains
a database of long URLs, each of which has a unique identifier.

=head1 Functions

=head2 makeashorterlink

The function C will call the L web site passing
it your long URL and will return the shorter version.

=head2 makealongerlink

The function C does the reverse. C
will accept as an argument either the full URL or just the identifier.

If anything goes wrong, then either function will return C.

=head2 EXPORT

makeashorterlink, makealongerlink

=head1 SUPPORT, LICENSE, THANKS and SUCH

See the main L docs.
