 Usage     : How to use this function/method
 Purpose   : What it does
 Returns   : What it returns
 Argument  : What it wants to know
 Throws    : Exceptions and other anomolies
 Comment   : This is a sample subroutine header.
           : It is polite to include more pod and fewer comments.

=head2 C<new()>

  Usage     : $self->block_new_method() within text_pm_file()
  Purpose   : Build 'new()' method as part of a pm file
  Returns   : String holding sub new.
  Argument  : $module: pointer to the module being built
              (as there can be more than one module built by EU::MM);
              for the primary module it is a pointer to $self
  Throws    : n/a
  Comment   : This method is a likely candidate for alteration in a subclass,
              e.g., pass a single hash-ref to new() instead of a list of
              parameters.
