NAME
    Env - perl module that imports environment variables as scalars or arrays

SYNOPSIS
        use Env;
        use Env qw(PATH HOME TERM);
        use Env qw($SHELL @LD_LIBRARY_PATH);

DESCRIPTION
    Perl maintains environment variables in a special hash named %ENV. For when this access method is inconvenient, the Perl module "Env" allows environment variables to be treated as scalar or array variables.
