**  MODULE
**
**      file: bibtex-3.c
**
**  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 is the third of 4 source modules for BibTeX.  The source has 
**      been split into 4 parts so that some of the more primitive editors
**      can cope.  This code mimics the BibTeX WEB source as closely as
**      possible and there should be NO system dependent code in any of the 
**      bibtex-#.c modules.
**
**      The functions defined in this module are:
**
**          pre_def_certain_strings
**          pre_define
**          print_lit
**          print_missing_entry
**          print_overflow
**          print_recursion_illegal
**          print_skipping_whatever_remains
**          print_stk_lit
**          print_wrong_stk_lit
**          push_lit_stk
**          quick_sort
**          sam_too_long_file_name_print
**          sam_wrong_file_name_print
**          scan1
**          scan1_white
**          scan2
**          scan2_white
**          scan3
**          scan_a_field_token_and_eat_whit
**          scan_alpha
**          scan_and_store_the_field_value
**          scan_balanced_braces
**          str_eq_buf
**          str_eq_str
**          str_lookup
**          swap
**          trace_and_stat_printing
**          trace_pr_fn_class
**          unknwn_function_class_confusion
**          unknwn_literal_confusion
**          upper_case
**          von_name_ends_and_last_name_sta
**          von_token_found
**          x_add_period

**  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.
