CamlTk releases

[Francois Rouaix <rouaix@cadet.inria.fr>]

I have made new releases for the CamlTk library available by anonymous FTP on
ftp://ftp.inria.fr/lang/caml-light/camltk


A brief reminder:
TK is a GUI library for the TCL language. Normally, TK is controlled
from TCL. The purpose of the CamlTk interface is to provide a Caml Light
library to control TK from Caml Light programs. Thus, TK can be used to
program graphical user-interfaces in Caml Light without knowledge of
the TCL language.

Since the last release (september 1995), CamlTk has been used extensively
in the MMM brower. This new release benefits from this experience: numerous
bugs have been fixed; performance has been enhanced; more Tk feature are
supported. It is still for Tk 4.0 though.

The directory contains two versions:
  * cltk.tar.gz is the library for Caml Light 0.71 (not tested with previous
  releases). It should be unpacked in the contrib/ directory of your Caml Light
  source distribution.

  * ocamltk.tar.gz is the library for Objective Caml. It should be unpacked
  in the otherlibs/ directory of your Objective Caml distribution.

The versions are almost identical, except for syntax differences between
the two Caml systems.
The Caml Light version has also a demonstration program (source browser for
Caml Light modules).
The Objective Caml version has bindings for BLT 1.8, support for
safe versions of the interface (used in Caml applets) and a file selection
dialog (contributed by Jun P. Furuse).

A printable documentation is also available in the same directory.
The on-line version of the documentation has not been updated yet.


REQUIREMENTS:
You must have  Caml Light 0.71 (not tested with previous releases) or 
Objective Caml.
You must have Tcl7.4/Tk4.0, preferably with patchlevel3. CamlTk will *not*
work with previous releases of Tcl/Tk (either 7.3/3.6 or beta versions of
7.4/4.0). CamlTk has not been tested with 7.5/4.1, and probably does not 
work as is with these versions.

UPGRADING:
Because I wanted to keep the Caml Light and Objective Caml versions as
close as possible, I had to report changes from the Objective Caml version
into the Caml Light version. In particular, both versions use the 
capitalisation rules of OCaml. As a consequence, the new CamlTk for
Caml Light is not fully compatible with the previous release. Upgrading
should be essentially a matter of moving some type names to lowercase,
and replacing "new" by "create" in some places (textvariables).

LIMITATIONS:
Don't even think of using CamlTk with threads in Objective Caml.
Be patient. We're working on it.
