Synopsis

     subsets {say "@_"} qw(a b c);

     #  a

Description
    Generate and process all the all the subsets of a list using the
    standard Perl metaphor.

    "subsets()" returns the number of subsets. Please note that this
    incloudes the empty set as it is a subset of all sets.

    "subsets()" is easy to use and fast. It is written in 100% Pure Perl.

    Please note that the order in which the subsets are generated is not
    guaranteed, so please do not rely on it.

Export
    The "subsets()" function is exported.

Installation
    Standard Module::Build process for building and installing modules:

      perl Build.PL
      ./Build
      ./Build test
      ./Build install

    Or, if you're on a platform (like DOS or Windows) that doesn't require
    the "./" notation, you can do this:

      perl Build.PL
      Build
      Build test
      Build install
