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

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

CONFIGURATION

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