DBOW is a database compiler-compiler or front-end.  It takes table
definitions in a relatively high-level language and prepares C,
C++, PHP, Perl (etc) functions for manipulating the database.  It
will also produce SQL table data for MySQL.

DBOW allows a user to define a database table in a meta-language
and produce SQL for generating the table.  It also provides C, C++,
PHP, Perl functions or methods for manipulating the table, such as
insert/delete/search/update.  The system is used to remove the
grunt-work of writing class libraries or access functions for
database tables and having to update several different source files
if the SQL table format should change.  The resultant code provides
a language-native mechanism for manipulating the database.

Currently it supports C, C++, SQL and PHP (with Perl under way).
It will be extended to support other languages and database constructs
as required. It currently compiles/runs on FreeBSD/Linux.  It doesn't
require any other libraries or elements except YACC/Bison.

	* Fixed a few bugs since the previous release and incorporated
	  the changes to the Perl module.

	* This is a minor update of the DBOW code to fix some bugs
	  found after 0.4 was released.  The biggest change is the
	  addition of nested queries so that dbow_query can be
	  called recursively without affecting the "upper" query.
	  Also added the stubs for supporting the 'function' block
	  which allows for a more granular approach to defining
	  functions.

	* This release of DBOW brings the C interface to a stable
	  (BETA) level, adds some new functionality and fixes a few
	  bugs in the back-end.  Added a 'db_findXXXfirst()' function
	  for searching the entire table.  Added a 'db_runXXXquery()'
	  function which will run an SQL statement (without parsing
	  any arguments) and return the first match.  Fixed a bug
	  where the include() m4 statement was being emitted more
	  than once.  Put the 'EMIT' code at the bottom of the
	  output file.

	* This version has support for C and SQL with the basics
	  of PHP support.  Perl needs to be added as does C++.

	* Extensive hacking to make the back-end use M4 instead of hard-coding
	  the output with printfs.

2004-01-28  dtynan  <dtynan@kalopa.com>

	* Modified the M4 back-end so that it uses looping rather than relying
	  on the front-end compiler to produce per-table fields.  This makes
	  the intermediate code cleaner and makes it a lot easier to write
	  advanced back-ends.  SQL is still hard-coded.

2004-04-30  dtynan  <dtynan@kalopa.com>

	* Added a 'db_findXXXfirst()' function for searching
	  the entire table.
	* Added a 'db_runXXXquery()' function which will run
	  an SQL statement (without parsing any arguments)
	  and return the first match.
	* Fixed a bug where the include() m4 statement was
	  being emitted more than once.
	* Put the 'EMIT' code at the bottom of the output file.

2004-05-18  dtynan  <dtynan@kalopa.com>

	* Deprecated the use of %proto and %code because they're
	  too hard to deal with in the midst of the M4 stuff.
	* Added new keywords %[type XXX] proto { and %[type XXX] code {
	  which will immediately emit the following lines from there
	  to the line "%}" either to the include file (or the code
	  file if there is no separate include file) and to the code
	  file respectively.
