=head1 NAME
MooseX::Getopt::Meta::Attribute::Trait - Optional meta attribute trait for custom option names
=head1 SYNOPSIS
package App;
use Moose;
with 'MooseX::Getopt';
has 'data' => (
traits => [ 'Getopt' ],
is => 'ro',
isa => 'Str',
default => 'file.dat',
# tells MooseX::Getopt to use --somedata as the
# command line flag instead of the normal
# autogenerated one (--data)
cmd_flag => 'somedata',
# tells MooseX::Getopt to also allow --moosedata,
# -m, and -d as aliases for this same option on
# the commandline.
cmd_aliases => [qw/ moosedata m d /],
# Or, you can use a plain scalar for a single alias:
cmd_aliases => 'm',
);
=head1 DESCRIPTION
This is a custom attribute metaclass trait which can be used to
specify a the specific command line flag to use instead of the
default one which L<MooseX::Getopt> will create for you.
=head1 METHODS
These methods are of little use to most users, they are used interally
within L<MooseX::Getopt>.

=item B<cmd_flag>
Changes the commandline flag to be this value, instead of the default,
which is the same as the attribute name.
=item B<cmd_aliases>
Adds more aliases for this commandline flag, useful for short options
and such.
