=head1 NAME
Config - access Perl configuration option
=head1 SYNOPSIS
use Config;
if ($Config{'cc'} =~ /gcc/) {
print "built by gcc\n";
}
=head1 DESCRIPTION
The Config module contains everything that was available to the
C<Configure> program at Perl build time. Shell variables from
F<config.sh> are stored in the readonly-variable C<%Config>, indexed by
their names.
=head1 EXAMPLE
Here's a more sophisticated example of using %Config:
use Config;
defined $Config{sig_name} || die "No sigs?";
foreach $name (split(' ', $Config{sig_name})) {
$signo{$name} = $i;
$signame[$i] = $name;
$i++;
}
print "signal #17 = $signame[17]\n";
if ($signo{ALRM}) {
print "SIGALRM is $signo{ALRM}\n";
}
=head1 NOTE
This module contains a good example of how to make a variable
readonly to those outside of it.

## do not forget to propagate your changes by running "Configure -der". You may
## instead choose to run each of the .SH files by yourself, or "Configure -S".
