New features in version 0.23.0
==============================

Counting versions has been changed. Different version numbers will not
be used any more. Version number for the whole package is stored in
`ddconfig.h' file.

Some bugs in configurator utility have been fixed.

`pcrosscl.h' and `pcross.cc' has been moved from parser.src
subdirectory into grp2c.src as `crosscl.h' and `cross.cc'.

New option `-t' has been added to `grppars' utility and `grp2c'
program. Using this option these programs generate task graph to
standard output. Format of the task graph is:

application name
process name1 otherprocess1 otherprocess2 ...
process name2 otherprocess1 otherprocess2 ...

GRP parser
----------

Task graph genberator has been introduced. New variable:
`TParser::ShowTask'. New methods: `TParser::ShowTasks',
`TprsAppColl::ShowTasks', `TprsApplication::ShowTasks'.

GRP code generator
------------------

A new option for `grp2c' has been intoduced. Using `-R dir' default
prefix directory can be overwritten. This directory is included into
the generated `Makefile' as the value of `prefix' variable.

Error handling has been improved. Return value of `GenCrossRef()'
function in `TProcess', `TItem', 'TItems', `TGraphItem' classes has
been changed to `bool'. Exit codes of `grp2c' program are:

  0 - success.
  1 - wrong option.
  2 - no execution required.
  3 - parser error.
  4 - code generation error.
  5 - Makefile generation error.
  6 - cross-file generation error.

Cross file generation has been redesigned. Some methods have been
deleted: `TItem::GenCrossRef', `TItems::GenCrossRef',
`TProcess::GenCrossRef', `TProcColl::GenCrossRef',
`TGraphItem::GenCrossRef'. Some new methods have been introduced:
`TComp::ItemCrossInfo'.

grp2c generates cross reference information in every case when a user
written code is inserted into the generated source. Every lines in
cross reference file has the following structure:

filename first last processname type

Where `filename' is name of the generated C-source file where the user
written code was inserted. `first' and `last' are line numbers of
begin and end of the inserted code. `processname' is the name of the
process which the generated code belongs to. `type' determines the
type of the cross reference information. If it is a positive number
then it identifies the program item number. -10 means that inserted
code was collected from heads section (probably include definitions),
-20 means global section, and -30 means local section.
