+=head1 NAME
+
+Errno - System errno constants
+
+=head1 SYNOPSIS
+
+ use Errno qw(EINTR EIO :POSIX);
+
+=head1 DESCRIPTION
+
+C<Errno> defines and conditionally exports all the error constants
+defined in your system C<errno.h> include file. It has a single export
+tag, C<:POSIX>, which will export all POSIX defined error numbers.
+
+C<Errno> also makes C<%!> magic such that each element of C<%!> has a non-zero
+value only if C<$!> is set to that value, eg
+
+ use Errno;
+
+ unless (open(FH, "/fangorn/spouse")) {
+ if ($!{ENOENT}) {
+ warn "Get a wife!\n";
+ } else {
+ warn "This path is barred: $!";
+ }
+ }
