/*
* This was inspired by an ISO fuzz tester written by Michal Zalewski
* and posted to the "vulnwatch" mailing list on March 17, 2005:
* http://seclists.org/vulnwatch/2005/q1/0088.html
*
* This test simply reads each archive image into memory, pokes
* random values into it and runs it through libarchive. It tries
* to damage about 1% of each file and repeats the exercise 100 times
* with each file.
*
* Unlike most other tests, this test does not verify libarchive's
* responses other than to ensure that libarchive doesn't crash.
*
* Due to the deliberately random nature of this test, it may be hard
* to reproduce failures. Because this test deliberately attempts to
* induce crashes, there's little that can be done in the way of
* post-failure diagnostics.
*/

* developed for other tests. */
