Macintosh perl scripts will have the appropriate Creator and
Type, so that double-clicking them will invoke the perl application.

+ $ exit++ + ++$status != 0 and $exit = $status = undef;
+
+at the top of your script, where C<-mysw> are any command line switches you
+want to pass to Perl. You can now invoke the script directly, by saying
+C<perl script>, or as a DCL procedure, by saying C<@script> (or implicitly
+via F<DCL$PATH> by just using the name of the script).
+
+This incantation is a bit much to remember, but Perl will display it for
+you if you say C<perl "-V:startperl">.
