The user may specify the B<-e> option to select the appearance of
the cow's eyes, in which case the first two characters of the
argument string I<eyes> will be used.  The default eyes are 'oo'.
The tongue is similarly configurable through B<-T>; it must be two
characters and does not appear by default.  However, it does appear
in the 'dead' and 'stoned' modes.  Any configuration done by B<-e>
and B<-T> will be lost if one of the provided modes is used.

The B<-f> option specifies a particular cow picture file ("cowfile")
to use.  If the cowfile spec contains a slash ("/") then it will
be interpreted as a path relative to the current directory.
Otherwise, cowsay will first search C<@INC> for installed cows
under the C<Acme::Cow::> hierarchy, and then search the path
specified in the C<COWPATH> environment variable.  To list all
cowfiles installed as modules (in C<@INC>) and on the current
C<COWPATH>, invoke cowsay with the B<-l> switch.

If the program is invoked as cowthink (or any word that has "think"
as a substring) then the cow will think its message instead of
saying it.

If you would like to write your own cow files, please consult
L<Acme::Cow> and the cowfiles provided with the distribution (in
the C<cows> subdirectory).

=head1 AUTHOR

Tony Monroe E<lt>tmonroe plus perl at nog dot netE<gt>.  Has been called
a freak many times for even thinking of such a piece of software,
let alone writing it.

The following have contributed cow files, directly or indirectly: 

Shannon Appel, Jordan K Hubbard, Donald Kubasak, Marshall Kirk
McKusick, Lincoln Myers, David Petrou, Anthony S Polito, Geordan
Rosario, Eric Rowe, Lars Smith, E<lt>pborys at p-soft dot silesia
dot linux dot org dot plE<gt>.

If your name is not on this list, and it should be, then feel free
to mail the author and remind him gently.

=head1 BUGS

tend to hang around cows.  Cows sometimes try to shoo them away
with their tails.

Bugs should be reported to the author as soon as they are found,
so he may correct them, or quickly write them off as user error.

=head1 HISTORY

Cowsay 1 (1996?) was a very limited cow, which only said things in
a particular format: I<subject> is I<verb>ing I<object>.  Cowsay
2 (1997?) overcame that limitation, and added alternate cow files,
and thought capabilities.  Cowsay 3 (1999) was a rewrite in Perl
5.  Cowsay 4 (2002) leverages Perl's object facilities to make the
author's life easier.
