Description
Generate and process all the permutations of a list using the standard
Perl metaphor.
"permute()" returns the number of permutations in both scalar and array
context.
"permute()" is easy to use and fast. It is written in 100% Pure Perl.
Please note that the order in which the permutations are generated is
not guaranteed, so please do not rely on it.
Export
The "permute()" 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
