Env - perl module that imports environment variables

SYNOPSIS

           use Env;
           use Env qw(PATH HOME TERM);

DESCRIPTION

       Perl maintains environment variables in a pseudo-hash
       named %ENV.  For when this access method is inconvenient,
       the Perl module Env allows environment variables to be
       treated as simple variables.

       The Env::import() function ties environment variables with
       suitable names to global Perl variables with the same
       names.  By default it does so with all existing
       environment variables (keys %ENV).  If the import function
       receives arguments, it takes them to be a list of
       environment variables to tie; it's okay if they don't yet
       exist.

       After an environment variable is tied, merely use it like
       a normal variable.  You may access its value

           @path = split(/:/, $PATH);

       or modify it

           $PATH .= ":.";

       however you'd like.  To remove a tied environment variable
       from the environment, assign it the undefined value

           undef $PATH;
