-=head1 NAME
-
-MooseX::Getopt - A Moose role for processing command line options
+1;
=head1 SYNOPSIS
like a normal C<ArrayRef> type for Getopt purposes (that is,
C<=s@>).
-=head1 METHODS
-
-=over 4
-
-=item B<new_with_options (%params)>
+=method B<new_with_options (%params)>
This method will take a set of default C<%params> and then collect
params from the command line (possibly overriding those in C<%params>)
C<new_with_options> will throw an exception.
If L<Getopt::Long::Descriptive> is installed and any of the following
-command line params are passed, the program will exit with usage
-information. You can add descriptions for each option by including a
+command line params are passed, the program will exit with usage
+information (and the option's state will be stored in the help_flag
+attribute). You can add descriptions for each option by including a
B<documentation> option for each attribute to document.
--?
--usage
If you have L<Getopt::Long::Descriptive> the C<usage> param is also passed to
-C<new>.
+C<new> as the usage option.
-=item B<ARGV>
+=method B<ARGV>
This accessor contains a reference to a copy of the C<@ARGV> array
as it originally existed at the time of C<new_with_options>.
-=item B<extra_argv>
+=method B<extra_argv>
This accessor contains an arrayref of leftover C<@ARGV> elements that
L<Getopt::Long> did not parse. Note that the real C<@ARGV> is left
un-mangled.
-=item B<meta>
-
-This returns the role meta object.

-=head1 BUGS
+B<Important>: By default, L<Getopt::Long> will reject unrecognized arguments
+(that is, arguments that do not correspond with attributes using the Getopt
+trait). To disable this, and allow the population of C<extra_argv>, enable the
+C<pass_through> option of L<Getopt::Long> for your class: C<use Getopt::Long
+qw(:config pass_through);>
-All complex software has bugs lurking in it, and this module is no
-exception. If you find a bug please either email me, or add the bug
-to cpan-RT.
+=method B<usage>
-=head1 AUTHOR
+This accessor contains the L<Getopt::Long::Descriptive::Usage> object (if

+This accessor contains the boolean state of the --help, --usage and --?

-=head1 COPYRIGHT AND LICENSE
+This does most of the work of C<new_with_options>, analyzing the parameters
+and argv, except for actually calling the constructor. It returns a
+L<MooseX::Getopt::ProcessedArgv> object. C<new_with_options> uses this
+method internally, so modifying this method via subclasses/roles will affect
+C<new_with_options>.

+See L<Getopt::Long#Configuring_Getopt::Long> for many other customizations you
+can make to how options are parsed. Simply C<use Getopt::Long qw(:config
+other_options...)> in your class to set these.
