+=head1 NAME
+
+kenny.pl -- translate from and to KennySpeak
+
+=head1 SYNOPSIS
+
+B<kenny.pl>
+S<[ B<-h> ]>
+S<[ B<-u> ]>
+S<[ B<-k> | B<-d> ]>
+S<[ I<file1> ] [ I<file2> ] ...>
+
+=head1 OVERVIEW
+
+kenny.pl translates a given text from or to B<KennySpeak>. KennySpeak
+looks like this:
+
+ "Ppfmfp ppmffm mfmppfmpm, fmpmfpmppffm'fpmmpp
+ pmpmffpmfpmfmppmpm Pmpmppppppppffm!"
+
+=head1 DESCRIPTION
+
+kenny.pl will read the given filenames, translate them and print the
+results on stdout. If you don't give a filename, stdin is used. A F<->
+as a filename means stdin.
+
+Without any parameters, kenny.pl will look at the first line of input
+and guess which way you want to translate. If kenny.pl guesses wrong,
+you must select the translation mode using the B<-k> or B<-d> switch.
+
+=head2 Switches
+
+=over 5
+
+=item B<-h>
+
+This will print a short notice and a quick summary of the available
+switches.
+
+=item B<-u>
+
+This will convert German umlauts to Ae, Oe, Ue, ae, oe, ue and ss
+so that they can be kennyfied correctly.
+
+=item B<-k>
+
+Kennyfy. This forces the input to be translated into KennySpeak.
+
+=item B<-d>
+
+Dekennyfy. This forces the input to be translated back from
+KennySpeak.
+
+=back
+
+=head1 VERSION
+
+This is $Revision: 1.7 $.
+
+=head1 BUGS
+
+The B<-u> switch might not work for charsets other than Latin-1. You
+might try to convert the kenny.pl script using B<recode> to change it
+from Latin-1 to your preferred charset.
+
+=head1 CREDITS

+newer versions of kenny.pl. Bug reports or comments about the program
+should be sent to him:

+
+Alan Eldridge <F<alane@geeksrus.net>> patched in a signal handler to
+print an appropriate message when kenny.pl is killed.
