 * ABSTRACT
 *
 * $Log: dbowint.h,v $
 * Revision 1.6  2004/06/25 14:57:23  dtynan
 * Fixed a bug in the C template where forloops weren't working properly.
 * Added a RELEASE file, first pass at a man-page, and the basic hooks
 * for dealing with th %function block.
 *
 * Revision 1.5  2004/05/18 11:18:48  dtynan
 * Deprecated the use of %proto and %code statements.  Also added new
 * keywords which will immediately emit the following block either to
 * the include file or to the code file respectively.
 *
 * Revision 1.4  2004/04/30 12:12:24  dtynan
 * Lots of changes for minor bug fixes, added functionality and the like.
 * Notably the following:
 *     o	Added a 'db_findXXXfirst()' function for searching the entired
 * 	table.
 *     o	Added a 'db_runXXXquery()' function which will run an SQL
 * 	statement (without parsing any arguments) and return the
 * 	first match.
 *     o	Fixed a bug where the include() m4 statement was being used
 * 	more than once.
 *     o	Put the 'EMIT' code at the bottom of the output file.
 *
 * Revision 1.3  2004/01/26 23:43:21  dtynan
 * Extensive changes to fix some M4 issues and some library issues.
 * Removed many of the functions which were used to parse data types
 * and made them inline instead.  Improved the M4 generator by adding
 * for loops.
 *
 * Revision 1.2  2003/11/17 13:15:20  dtynan
 * Various changes to fix errors in the back-end code.
 *
 * Revision 1.1  2003/10/14 13:00:26  dtynan
 * Major revision of the DBOW code to use M4 as a back-end instead of
 * hard-coding the output.
