This file contains important information about TLX 5.0. Please read it
carefully.


Development status
------------------

	TLX is still under active development. As such, expect changes to
	the code and occasional bugs. Also, printed documentation is not yet
	available, but will be provided in the near future.

	- Refer to the file CHANGES.TXT for changes in the library since
	  earlier versions, in particular version 4.2.

	- Refer to the file BUGS.TXT for a list of known problems.


Supported compilers
-------------------

	TLX currently supports the following C++ compilers:

	- Borland C++ (DOS, Windows, OS/2)
	- IBM C Set++ (OS/2)
	- Symantec C++ (DOS, Windows)
	- Watcom C++ (DOS, Windows, OS/2)

	The following compilers will be supported when available:

	- Microsoft Visual C++ 2.0

	Support for the following compilers has been DROPPED, usually because
	the compilers are no longer up to date with respect to current C++
	standards:

	- Microsoft Visual C++ 1.5 and earlier
	- THINK C++ (Macintosh)
	- Zortech C++ (DOS, Windows, OS/2)

	Refer to COMPILE.TXT for more details about supported compilers.


Unsupported compilers
---------------------

	If you use a C++ compiler that is not currently supported, chances
	are that you will see messages during compilation stating that the
	compiler isn't supported, or that the platform under which you are
	compiling is not known. In those cases, please contact Tarma Software
	Research; we may be able to help you out and perhaps add your
	compiler/platform combination to the list of supported compilers.


Major changes in TLX 5.0
------------------------

	The following changes are implemented or planned for this release
	(* indicates partially implemented as of this release, ** indicates
	not implemented yet):

	- Integration of the latest C++ features (exception handling, RTTI,
	  standard classes, various smaller language issues). There will
	  be limited transition support for C++ compilers that do not yet
	  implement all these features.

**	- If and when C++ namespaces are introduced, we will immediately
	  adopt them, using 'Tlx' as the base namespace within which all
	  all other TLX namespaces will be embedded.

*	- Several new or improved classes in the following areas: memory
	  management, backtrack searching and constraint propagation,
	  abstract data structures.

*	- Introduction of iterator classes for all collection classes and
	  a few standard C vector idioms.

**	- Support for multi-threaded applications.

	- Changes in naming conventions. (There is a migration tool, called
	  TLX5UP.EXE, to help you cope with these changes. Read CHANGES.TXT
	  for more information about this tool.)

**	- Full documentation.

	Refer to the file CHANGES.TXT for more details.
