demo

demo /de'moh/  [short for `demonstration'] 1. v. To
   demonstrate a product or prototype.  A far more effective way of
   inducing bugs to manifest than any number of {test} runs,
   especially when important people are watching.  2. n. The act of
   demoing.  "I've gotta give a demo of the drool-proof interface;
   how does it work again?"  3. n. Esp. as `demo version', can
   refer either to an early, barely-functional version of a program
   which can be used for demonstration purposes as long as the
   operator uses *exactly* the right commands and skirts its numerous
   bugs, deficiencies, and unimplemented portions, or to a special
   version of a program (frequently with some features crippled) which
   is distributed at little or no cost to the user for enticement
   purposes.
