New features in version 0.31.0
==============================

GRP Parser
----------

Parser has been revised. `IntParam', `StringParam', `Identifier',
`PHeaderType', `ProgType', `ParserInst', `ParserStrs', `ParserPtrs',
`NameMod' and `FloatParam' fields and `ModifyName' method have been
removed from `TParser' class.

`ProgramSection' rule has been renamed to `Process', and original
`ProgramSection' has been changed to

ProgramSection::= Process | ProcessGroup.

New rule has been introduced for process group:

ProcessGroup::= "PROCGROUP" ProcessNumID ":" ID "{" ProgramSList "}".

`TprsProcess' class has been extended with a new field, called
`Rank'. This field is used to hold rank number associated to the
process.

New port types have been introduced: multicast, scatter, reduce and
gather. These are for ports of the process groups.

`TprsPort' class hes been extended with a new field (Computation) to
store type of the computation which must be done by the port if it is
a reduce port. Another field, `Name' has been added to store name of
the port and `ProcID' to store numerical ID of connected process if it
is defined by its ID instead of its name. Constructor of the
`TprsPort' class has been changed to accept initial values of the new
fields. 

`ProcSgroup' rule has been changed from

ProcSgroup::= PortType ":" IntNumber PortDefToPort.

to

ProcSgroup::= PortType "(" Calculation ")" ":" IntNumber PortDefToPort.

`PortDefToProcID' rule has been changed from:

PortDefToProcID::= | IntNumber.

to:

PortDefToProcID::= | ID	| IntNumber.

New methods in `TprsProcColl' class: `FoundProcByID', `FoundProc'.

C or C++ style comments can be used in GRP files. Nested C comments
are not allowed.
