<p>
A <a class="link" href="CattleProgram.html" title="CattleProgram"><span class="type">CattleProgram</span></a> represents a complete Brainfuck program, that is,
the instructions to be executed and possibly its input.
</p>
<p>
The input for a program can optionally be specified in the source
file, and it's separated from the program code by a bang (!)
symbol. For example, given the following input:
</p>
<p>
</p>
<div class="informalexample"><pre class="programlisting">
,+.!sometext
</pre></div>
<p>
</p>
<p>
the program's code is ",+." while the program's input is
"sometext".
</p>
<p>
Any Brainfuck instruction after the bang symbol is considered part
of the input, and as such is not executed. Subsequent bang symbols
are also considered part of the input.
