Caveats

       This module has only a subset of Math::Random subroutines (contributions welcome), implemented using
       either Perl core subroutines or other well-known modules. Thus Math::Random::Free is neither as complete,
       nor as fast, nor as random as Math::Random.  Also Math::Random::Free does not aim for cryptographic
       security.

       While Math::Random::Free supports seed setting, it does that differently from Math::Random. It means that
       one should not expect the same seed producing identical random sequences in both modules.

       As Math::Random::Free employs List::Util for producing random permutations, these are influenced by
       $List::Util::RAND variable.

Description

       This is free (see below) implementation of Math::Random 0.72, serving as drop-in replacement for this
       module.

Motivation

       Math::Random is a great and widely-used module for the generation of random numbers and permutations.
       Despite being open-source, Math::Random does not fulfill free open-source software definitions as
       established by the Open Source Initiative (<https://opensource.org/osd>) and the Debian Project
       (<https://www.debian.org/social_contract#guidelines>, a.k.a. DFSG). This is mostly because "randlib" code
       cannot be copied nor distributed for direct commercial advantage. Math::Random::Free is created to free
       the code depending on Math::Random from these limitations.
