=head1 VERSION

version 0.68

=head1 SYNOPSIS

  package My::App;
  use Moose;
  with 'MooseX::Getopt::Dashes';

  # Will be called as --some-thingy, not --some_thingy
  has 'some_thingy' => (
      is      => 'ro',
      isa     => 'Str',
      default => 'foo'
  );

  # Will be called as --another_thingy, not --another-thingy
  has 'another_thingy' => (
      traits   => [ 'Getopt' ],
      cmd_flag => 'another_thingy'
      is       => 'ro',
      isa      => 'Str',
      default  => 'foo'
  );

  # use as MooseX::Getopt

=head1 DESCRIPTION

This is a version of L<MooseX::Getopt> which converts underscores in
attribute names to dashes when generating command line flags.

You can selectively disable this on a per-attribute basis by supplying
a L<cmd_flag|MooseX::Getopt::Meta::Attribute/METHODS> argument with
the command flag you'd like for a given attribute. No underscore to
dash replacement will be done on the C<cmd_flag>.
