NAME

  Perl::Exactly - ensures exactly version of perl

SYNOPSIS

  use Perl::Exactly 5.005; # ensures perl is 5.005
  use Perl::Exactly 5.016; # ensures perl is 5.016, but doesn't "use strict" and "use feature"

DESCRIPTION

  Perl::Exactly ensures that perl interpreter matches to required version
  exactly. If running perl doesn't match required version then Perl::Exactly
  finds it using Perl/Exactly.pm.conf, and executes script again on it.
  When exactly version of perl not found, script will die.

INSTALLATION

  1. Copy Perl/Exactly.pm and Perl/Exactly.pm.conf to @INC directory.

CONFIGURATION

  1. Edit Perl/Exactly.pm.conf to define paths of perls.
