/*
* This file is a (rather silly) demonstration of the use of the
* C Dynamic Object library. It is a also reasonably thorough test
* of the library (except that it only tests it with one data size).
*
* There are no restrictions on this code; however, if you make any
* changes, I request that you document them so that I do not get
* credit or blame for your modifications.
*
* Written by Barr3y Jaspan, Student Information Processing Board (SIPB)
* and MIT-Project Athena, 1989.
*
* 2002-07-17 Moved here from util/dyn/test.c. Older changes described
* at end of file; for newer changes see ChangeLog.
