=head1 NAME

ExtUtils::ModuleMaker::Opts - Process command-line options for F<modulemaker>

=head1 SYNOPSIS

    use ExtUtils::ModuleMaker::Opts;

    $eumm_package = q{ExtUtils::ModuleMaker};
    $eumm_script  = q{modulemaker};
    
    $opt = ExtUtils::ModuleMaker::Opts->new(
        $eumm_package,
        $eumm_script,
    );
    
    $mod = ExtUtils::ModuleMaker::Interactive->new(
        $opt->get_standard_options()
    );

=head1 DESCRIPTION

The methods in this package provide processing of command-line options for 
F<modulemaker>, the command-line utility associated with Perl extension
ExtUtils::ModuleMaker, and for similar utilities associated with Perl
extensions which subclass ExtUtils::ModuleMaker.

=head1 METHODS

=head2 C<new()>

  Usage     : $opt = ExtUtils::ModuleMaker::Opts->new($package,$script) from
              inside a command-line utility such as modulemaker
  Purpose   : Creates an ExtUtils::ModuleMaker::Opts object
  Returns   : An ExtUtils::ModuleMaker::Opts object
  Argument  : Two arguments:
              1. String holding 'ExtUtils::ModuleMaker' or a package
              subclassed therefrom, e.g., 'ExtUtils::ModuleMaker::PBP'.
              2. String holding 'modulemaker' or the name of a command-line
                 utility similar to 'modulemaker' and found in the 
                 'scripts/' directory of the distribution named in 
                 argument 1

=head2 C<get_standard_options()>

  Usage     : %standard_options = $opt->get_standard_options from
              inside a command-line utility such as modulemaker
  Purpose   : Provide arguments to ExtUtils::ModuleMaker::Interactive::new()
              or to the constructor of the 'Interactive' package of a 
              distribution subclassing ExtUtils::ModuleMaker
  Returns   : A hash suitable for passing to 
              ExtUtils::ModuleMaker::Interactive::new() or similar constructor
  Argument  : n/a
