=head1 DESCRIPTION

Want to start developing the wrong way?

Use this module as your base! 

Write all your end code first and decide
each time you run your code which methods you want
to be able to store data into.

=head1 WHY?

Because acme told me to, this mess has been brought
to you by the letter L and the colour Orange.

=head1 PROBLEMS?

Only if someone finds a 'good' use for this module.
