+Installing cowsay
+=================
+
+If you really want to get things installed a nice and pretty way,
+
+ sh install.sh
+
+It will ask approximately one question. If you can't answer it,
+you need serious help.
+
+If the install goes well, you can start cowing immediately! Just
+be sure to read the manual page first...

+===========
+cowsay 3.03
+===========
+
+cowsay is a configurable talking cow, written in Perl. It operates
+much as the figlet program does, and it written in the same spirit
+of silliness.
+
+cowsay is actually a pretty old program. It has not really been
+released before, and I am releasing it in the hope that someone
+other than myself will be amused by it.
+
+The first major version of cowsay had one cow and one message
+template: $foo is $verb $bar. Not very flexible, but people managed
+to do pretty interesting things with it. The second major version
+scrapped many of the limitations of the first, by allowing arbitrary
+messages, multiple cowfiles, and even support for cows talking in
+figlet. The third version was a rewrite of the second into Perl
+5, whereupon the code got a lot smaller and more manageable. :-)
+
+If you are using Perl 5.004, you may have problems with Text::Wrap.
+(Yeesh, this module changes more than it should...) I've included
+a diff for the Text::Wrap (version 97.011701) that is shipped with
+5.004_04; the concept is simple enough that even older Perls can
+take advantage of this silly little patch; if there is a "sub fill"
+in the documentation for the module, copy it to a more useful
+section of that file. If not, just take "sub fill" wholesale from
+the patch. Oh, and consider upgrading to 5.005_03 or later.
+Please. You'll like it, I promise.
+
+To install cowsay, consult the INSTALL file in this directory.
+
+For the terms and conditions of use, consult the LICENSE file in
+this directory.
+

+.SH SYNOPSIS
+cowsay
+.RB [ \-e
+.IR eye_string ]
+.RB [ \-f
+.IR cowfile ]
+.RB [ \-h ]
+.RB [ \-l ]
+.RB [ \-n ]
+.RB [ \-T
+.IR tongue_string ]
+.RB [ \-W
+.IR column ]
+.RB [ \-bdgpstwy ]
+.SH DESCRIPTION
+.I Cowsay
+generates an ASCII picture of a cow saying something provided by the
+user. If run with no arguments, it accepts standard input, word-wraps
+the message given at about 40 columns, and prints the cow saying the
+given message on standard output.
+.PP
+To aid in the use of arbitrary messages with arbitrary whitespace,
+use the
+.B \-n
+option. If it is specified, the given message will not be
+word-wrapped. This is possibly useful if you want to make the cow
+think or speak in figlet(6). If
+.B \-n
+is specified, there must not be any command-line arguments left
+after all the switches have been processed.
+.PP
+The
+.B \-W
+specifies roughly (where the message should be wrapped. The default
+is equivalent to
+.B \-W 40
+i.e. wrap words at or before the 40th column.
+.PP
+If any command-line arguments are left over after all switches have
+been processed, they become the cow's message. The program will not
+accept standard input for a message in this case.
+.PP
+There are several provided modes which change the appearance of the
+cow depending on its particular emotional/physical state. The
+.B \-b
+option initiates Borg mode;
+.B \-d
+causes the cow to appear dead;
+.B \-g
+invokes greedy mode;
+.B \-p
+causes a state of paranoia to come over the cow;
+.B \-s
+makes the cow appear thoroughly stoned;
+.B \-t
+yields a tired cow;
+.B \-w
+is somewhat the opposite of
+.BR \-t ,
+and initiates wired mode;
+.B \-y
+brings on the cow's youthful appearance.
+.PP
+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 eye_string
+will be used. The default eyes are 'oo'. The tongue is similarly
+configurable through
+.B \-T
+and
+.IR tongue_string ;
+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.
+.PP
+The
+.B \-f
+option specifies a particular cow picture file (``cowfile'') to
+use. If the cowfile spec contains '/' then it will be interpreted
+as a path relative to the current directory. Otherwise, cowsay
+will search the path specified in the
+.B COWPATH
+environment variable.
+To list all cowfiles on the current
+.BR COWPATH ,
+invoke
+.B \*(nm
+with the
+.B \-l
+switch.
+.PP
+If the program is invoked as
+.B cowthink
+then the cow will think its message instead of saying it.
+.PP
+.SH COWFILE FORMAT
+A cowfile is made up of a simple block of
+.BR perl (1)
+code, which assigns a picture of a cow to the variable
+.BR $the_cow .
+Should you wish to customize the eyes or the tongue of the cow,
+then the variables
+.B $eyes
+and
+.B $tongue
+may be used. The trail leading up to the cow's message balloon is
+composed of the character(s) in the
+.B $thoughts
+variable. Any backslashes must be reduplicated to prevent
+interpolation. The name of a cowfile should end with
+.BR .cow ,
+otherwise it is assumed not to be a cowfile. Also, at-signs (``@'')
+must be backslashed because that is what Perl 5 expects.
+.PP
+.SH COMPATIBILITY WITH OLDER VERSIONS
+.PP
+What older versions? :-)
+.PP
+Version 3.x is fully backward-compatible with 2.x versions. If
+you're still using a 1.x version, consider upgrading. And tell me
+where you got the older versions, since I didn't exactly put them
+up for world-wide access.
+.PP
+Oh, just so you know, this manual page documents version \*(Vn of
+cowsay.
+.SH ENVIRONMENT
+The COWPATH environment variable, if present, will be used to search
+for cowfiles. It contains a colon-separated list of directories,
+much like
+.B PATH or
+.BR MANPATH .
+It should always contain the
+.B /usr/local/share/cows
+directory, or at least a directory with a file called
+.B default.cow
+in it.
+.SH FILES
+.B %PREFIX%/share/cows
+holds a sample set of cowfiles. If your
+.B COWPATH
+is not explicitly set, it automatically contains this directory.
+.SH BUGS
+If there are any, please notify the author at the address below.
+.SH AUTHOR
+Tony Monroe (tony@nog.net), with suggestions from Shannon
+Appel (appel@CSUA.Berkeley.EDU) and contributions from Anthony Polito
