/*----------------------------------------------------------------------
 * Module name:    hash.h
 * Author name:    Zachary Smith
 * Create date:    1 Sept 2000
 * Purpose: Shared string storage. This yields an approximate average 35%
 *   improvement of memory used for string storage against original file
 *   size (372 random rtfs from the internets, 200 MB). Some shrink a
 *   lot, some actually inflate.
 *----------------------------------------------------------------------
 * Changes:
 * 29 Mar 05, daved@physiol.usyd.edu.au: changes requested by ZT Smith
 * 06 Jan 06, marcossamaral@terra.com.br: changes hash_stats() 
 * 16 Dec 07, daved@physiol.usyd.edu.au: updated to GPL v3
 * 07 Oct 11, jf@dockes.org, added _HASH_H_INCLUDED_
 * Further: see VCS log
