=head1 NAME
English - use nice English (or awk) names for ugly punctuation variables
=head1 SYNOPSIS
    use English;
    ...
    if ($ERRNO =~ /denied/) { ... }
=head1 DESCRIPTION
This module provides aliases for the built-in variables whose
names no one seems to like to read.  Variables with side-effects
which get triggered just by accessing them (like $0) will still 
be affected.
For those variables that have an B<awk> version, both long
and short English alternatives are provided.  For example, 
the C<$/> variable can be referred to either $RS or 
$INPUT_RECORD_SEPARATOR if you are using the English module.
See L<perlvar> for a complete list of these.
