=head1 NAME

Test::File::ShareDir::Utils - Simple utilities for File::ShareDir testing

=head1 VERSION

version 1.001002

=head1 SYNOPSIS

use Test::File::ShareDir::Utils qw( extract_dashes );

my $hash = extract_dashes('dists', $oldhash );

=head1 EXPORTABLE FUNCTIONS

=head2 extract_dashes

A utility that helps transform:

-opt_a => bar
  -opt_b => baz
  NameA  => NameAValue
  NameB  => NameBValue

Into

opt_a => bar
  opt_b => baz
  modules => {
    NameA => NameAValue
    NameB => NameBValue
  }

This is a useful approach used all over import and functional style interfaces due to explicit configuration
being needed only on rare occasions.
