+=head1 NAME
+
+Config - access Perl configuration information
+
+=head1 SYNOPSIS
+
+ use Config;
+ if ($Config{'cc'} =~ /gcc/) {
+ print "built by gcc\n";
+ }
+
+ use Config qw(myconfig config_sh config_vars config_re);
+
+ print myconfig();

+ print config_re();
+
+ config_vars(qw(osname archname));
+
+
+=head1 DESCRIPTION
+
+The Config module contains all the information that was available to
+the C<Configure> program at Perl build time (over 900 values).
+
+Shell variables from the F<config.sh> file (written by Configure) are
+stored in the readonly-variable C<%Config>, indexed by their names.
+
+Values stored in config.sh as 'undef' are returned as undefined
+values. The perl C<exists> function can be used to check if a
+named variable exists.
+
+=over 4
+
+=item myconfig()
+
+Returns a textual summary of the major perl configuration values.
+See also C<-V> in L<perlrun/Switches>.
+
+=item config_sh()
+
+Returns the entire perl configuration information in the form of the
+original config.sh shell variable assignment script.
+
+=item config_re($regex)
+
+Like config_sh() but returns, as a list, only the config entries who's
+names match the $regex.
+
+=item config_vars(@names)
+
+Prints to STDOUT the values of the named configuration variable. Each is
+printed on a separate line in the form:
+
+ name='value';
+
+Names which are unknown are output as C<name='UNKNOWN';>.
+See also C<-V:name> in L<perlrun/Switches>.
+
+=back
+
+=head1 EXAMPLE
+
+Here's a more sophisticated example of using %Config:
+
+ use Config;
+ use strict;
+
+ my %sig_num;
+ my @sig_name;
+ unless($Config{sig_name} && $Config{sig_num}) {
+ die "No sigs?";
+ } else {
+ my @names = split ' ', $Config{sig_name};
+ @sig_num{@names} = split ' ', $Config{sig_num};
+ foreach (@names) {
+ $sig_name[$sig_num{$_}] ||= $_;
+ }
+ }
+
+ print "signal #17 = $sig_name[17]\n";
+ if ($sig_num{ALRM}) {
+ print "SIGALRM is $sig_num{ALRM}\n";
+ }
+
+=head1 WARNING
+
+Because this information is not stored within the perl executable
+itself it is possible (but unlikely) that the information does not
+relate to the actual perl binary which is being used to access it.
+
+The Config module is installed into the architecture and version
+specific library directory ($Config{installarchlib}) and it checks the
+perl version number when loaded.
+
+The values stored in config.sh may be either single-quoted or
+double-quoted. Double-quoted strings are handy for those cases where you
+need to include escape sequences in the strings. To avoid runtime variable
+interpolation, any C<$> and C<@> characters are replaced by C<\$> and
+C<\@>, respectively. This isn't foolproof, of course, so don't embed C<\$>
+or C<\@> in double-quoted strings unless you're willing to deal with the
+consequences. (The slashes will end up escaped and the C<$> or C<@> will
+trigger variable interpolation)
+
+=head1 GLOSSARY
+
+Most C<Config> variables are determined by the C<Configure> script
+on platforms supported by it (which is most UNIX platforms). Some
+platforms have custom-made C<Config> variables, and may thus not have
+some of the variables described below, or may have extraneous variables
+specific to that particular port. See the port specific documentation
+in such cases.
