Description

Generate all the permutations of a partitioned list using the standard Perl metaphor.

permutePartitions() returns the number of permutations in both scalar and array context.

permutePartitions() is written in 100% Pure Perl.

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
