=head1 NAME

Getopt::Long::Modern - Use Getopt::Long with modern defaults

=head1 SYNOPSIS

 use Getopt::Long::Modern;
 GetOptions(
   "f|foo=i" => \my $foo,
   "b|bar"   => \my $bar,
   "Z|baz=s" => \my @baz,
 );

=head1 DESCRIPTION

L<Getopt::Long::Modern> is a simple wrapper of L<Getopt::Long> to reduce the
amount of typing needed to get modern defaults, and to avoid having to remember
the correct incantations. See L<Getopt::Long/"Summary of Option Specifications">
for details on specifying options using L<Getopt::Long>.

Only the C<GetOptions> function from L<Getopt::Long> is exported. Additional
L<Getopt::Long> configuration may be passed as import parameters.

 use Getopt::Long::Modern qw(auto_help auto_version pass_through);

For any more advanced usage, you should probably use L<Getopt::Long> directly.
The equivalent L<Getopt::Long> configuration to using this module is:

 use Getopt::Long qw(:config gnu_getopt no_ignore_case);

=head1 DEFAULTS

L<Getopt::Long::Modern> currently sets the following configuration options by
default. See L<Getopt::Long/"Configuring Getopt::Long"> for more details on
available configuration.

=head2 gnu_getopt

This sets C<gnu_compat> to allow C<--opt=> for setting an empty string option,
C<bundling> to allow short options to be bundled together, C<permute> to allow
specifying options before or after other arguments, and C<no_getopt_compat> to
disallow C<+> for specifying options.

=head2 no_ignore_case

This makes all options case-sensitive, which is expected and required when
explicitly specifying short options of the same character but different case.
