New features in version 0.26.0
==============================

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

Bug in `grppars' utility has been fixed. `grppars' crashed if it was
started without parameters because it did not stop to work in this
case. 

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

Generation of C-source files has been changed to support the new
`grptyps.h' header file.

Generated server process has been changed to support new version on
`grp_create_proc' function.

Generated server process has been modified to use new `ReadMapFile'
function to read mapping information into `ProcessInfo' array. This
step is ignored if -m option is used to start the server program of
the application.

Bug in generated process code has been fixed. If there are more than
one channels are defined between two processes and the directions of
the channels are same, grp2c produces different name to identify
them. 

GRP library
-----------

New function `grp_stop_process' has been introduced. It is for server
process only.

New header file called `grptyps.h' has been created in `grapnel.src'
subdirectory. It will be used to store type definitions of the grapnel
library (target --eg. pvm-- independent types only).

Definition of `TProcessInfo' type has been moved from `grpdef.h' into
`grptyps.h'. It has been extended with a new element `cpu' which is
pointer to a string which contains name of the host or cpu resource
where the process should be started on.

Parameters of the `grp_cretae_proc' have been changed: `start_clock',
`task', `lista', and `no' parameters have been removed and a new
parameter `pinf' has been introduced. Type of `pinf' is
`TProcessInfo'. It is a structure which contains every information
about processes, such as name, parameters, etc.

`Init' function of the DDstuff library has been changed to support -m
option. Using option server process skips reading of the mapping file
and starts every processes on the default (chosen by the target
system) host. Meaning of the -f option has been extented. If server
process is unable to start any processes it stops others that are
started successfully and then exits. Using -f option, server process
continues to work.

DDstuff library has been extended with a new function `ReadMapFile'
which used by the server process to read mapping file and modify
`ProcessInfo' array with host names where the processes should be
started on. Mapping file is $OBJDIR/appname.map or ./appname.map if
OBJDIR variable is undefined.
