         Build line-oriented command interpreters.</A>

<P>

<P>
The <tt class=class>Cmd</tt> class provides a simple framework for writing
line-oriented command interpreters.  These are often useful for
test harnesses, administrative tools, and prototypes that will
later be wrapped in a more sophisticated interface.

<P>
<dl><dt><b><a name="l2h-831"><tt class=class>Cmd</tt></a></b> ()
<dd>
A <tt class=class>Cmd</tt> instance or subclass instance is a line-oriented
interpreter framework.  There is no good reason to instantiate
<tt class=class>Cmd</tt> itself; rather, it's useful as a superclass of an
interpreter class you define yourself in order to inherit
<tt class=class>Cmd</tt>'s methods and encapsulate action methods.
