This is the release 0.7 of the Caml Light system, for the Macintosh.
This archive contains the binary distribution: standalone application and
related files.
See also the source distribution, which contains all the files needed to
recompile Caml Light from scratch. If you want to use Caml Light under
MPW, you will have to get the source distribution and recompile Caml Light.
OVERVIEW:
Caml Light is a small, portable implementation of the ML language
that runs on most Unix machines. It has also been ported to the
Macintosh, the PC, and other microcomputers.
Caml Light implements the Caml language, a functional language from
the ML family. Caml is quite close to Standard ML, though not strictly
conformant. There are some slight differences in syntax and semantics,
and major differences in the module system (these changes were
required to support separate compilation).
Caml Light is implemented as a bytecode compiler, and fully
bootstrapped. The runtime system and bytecode interpreter is written
in standard C, hence Caml Light is easy to port to almost any 32 or 64 bit
platform. The whole system is quite small: about 200K for the runtime
system, and another 100K of bytecode for the compiler. 4 megabytes of
memory is enough to recompile the whole system. This stands in sharp
contrast with other implementations of ML, such as SML-NJ, that
requires about ten times more memory. Performance is quite good for a
bytecoded implementation: five to ten times slower than SML-NJ.
Caml Light comes in two flavors: a classical, interactive, toplevel-based
system in a standalone application; and an MPW tool compiler that produces
MPW tools. The former is good for learning the language and testing programs.
The latter is for use with Apple's MPW programming environment.
The application and the tools are all provided as "fat binaries": they will
run in native mode on both 68000-based and PowerPC-based macintoshes.
This distribution has been tested under system version 7.5.1 and 6.0.8,
on the following machines:
Mac Plus
PowerBook 520
Power Mac 7100/80av

DOCUMENTATION:
The Caml Light system is described in:
"The Caml Light system, release 0.7", by Xavier Leroy (reference manual)
"Functional programming using Caml Light", by Michel Mauny (tutorial)
These documents are distributed in Postscript, DVI, and plain text.
They can be obtained by anonymous FTP from ftp.inria.fr as described below.

directory: lang/caml-light
KEEPING IN TOUCH WITH THE CAML COMMUNITY:
There exists a mailing list of users of the Caml and Caml Light
systems developed at INRIA. The purpose of this list is to share
experience, exchange ideas (and even code), and report on applications
of the Caml language. This list is moderated; messages can be
written in English or in French. The list has about 200 subscribers.
Messages to the list should be sent to:
caml-list@margaux.inria.fr
If you wish to subscribe to this list, please send a message
(including your email address) to:
caml-list-request@margaux.inria.fr
The Usenet news group comp.lang.ml also contains discussions about
the ML family of programming languages, including Caml. The newsgroup
is moderated. For those without Usenet access, this newsgroup is
also accessible via a mailing list (to subscribe:
sml-list-request@cs.cmu.edu, to post a message: sml-list@cs.cmu.edu).
BUG REPORTS AND USER FEEDBACK:
Send your bug reports by E-mail to
caml-light@pauillac.inria.fr
or by paper mail to
Caml Light, projet Formel

To be effective, bug reports should include a complete program (preferably
small) that exhibits the unexpected behavior, and the configuration
you are using (machine type, etc).
The mailing list caml-light@pauillac.inria.fr is forwarded to a small
group of implementors at INRIA. For general questions and discussions,
caml-list@pauillac.inria.fr is better; for bug reports and very specific
technical questions, caml-light@pauillac.inria.fr is preferred. We often
