  12. =head1 NAME
  13.  
  14. Config - access Perl configuration option
  15.  
  16. =head1 SYNOPSIS
  17.  
  18.     use Config;
  19.     if ($Config{'cc'} =~ /gcc/) {
  20.     print "built by gcc\n";

  23. =head1 DESCRIPTION
  24.  
  25. The Config module contains everything that was available to the
  26. C<Configure> program at Perl build time.  Shell variables from
  27. F<config.sh> are stored in the readonly-variable C<%Config>, indexed by
  28. their names.
  29.  
  30. =head1 EXAMPLE
  31.  
  32. Here's a more sophisticated example of using %Config:
  33.  
  34.     use Config;
  35.  
  36.     defined $Config{sig_name} || die "No sigs?";
  37.     foreach $name (split(' ', $Config{sig_name})) {
  38.     $signo{$name} = $i;
  39.     $signame[$i] = $name;
  40.     $i++;
  41.     }   
  42.  
  43.     print "signal #17 = $signame[17]\n";
  44.     if ($signo{ALRM}) { 
  45.     print "SIGALRM is $signo{ALRM}\n";
  46.     }   
  47.  
  48. =head1 NOTE
  49.  
  50. This module contains a good example of how to make a variable
  51. readonly to those outside of it.

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