+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.
