âplenvâ ã brand new perl5 installation management tool⪠ã Hi, I implemented brand new perl5 installation management tool named plenv. from rbenv plenv is inspired from rbenv, from ruby world. rbenv provides a missing feature in perlbrew, it can use .ruby-version file to manage project local perl module. Use .perl-version!! With plenv, when you put a .perl-version file to ~/dev/MyProj/.perl-version
