**
**  DESCRIPTION
**
**      A 32-bit implementation of BibTeX v0.99c for MS-DOS, OS/2 2.x, 
**      Unix and VMS.  This C language implementation is based on the 
**      original WEB source but it has been enhanced to support 8-bit input
**      characters and a very large processing capacity.
**
**      For documentation describing how to use and build this program, 
**      see the 00README.TXT file that accompanies this distribution.
**
**  MODULE CONTENTS
**
**      This module defines the data types used in the BibTeX WEB source.  C
**      isn't as flexible as PASCAL when defining data types, so some of the
**      types defined are fairly abitrary.
**
**      There are particular problems when defining data types for variables
**      that will be used for indexing arrays.  Whilst the "short" data
**      type will often suffice, "unsigned short" has to be used to index
**      the string pool, which has 65,000 elements.  Care must be taken when 
**      mixing signed and unsigned values, especially if the signed value
**      can be negative.
**
**  AUTHORS

**  ACKNOWLEDGEMENT
**      
**      The original BibTeX was written by Oren Patashnik using Donald 
**      Knuth's WEB system.  This format produces a PASCAL program for 
**      execution and a TeX documented version of the source code. This 
**      program started as a (manual) translation of the WEB source into C.
