=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.
