I think it's best to subscribe tex-live-ml.

I just subscribed.... hope it will be avialbale soon.

Today I did copy texlive from DVD to my Mac-HD.
On the Mac (Powerbook) I heard a lot of noise too.
I think the DVD is mechanically ugly... it made noise even when
I didn't read from the CD.
But after starting the   cp -r   I heard a lot of
head repositioning.
That's ugly too.

One thing that on the tex-dl was brought in as ideas
was, to have an DVD-image cretaed by creating it in an
alphabetical order and during installation, reading it

But four hours installation time....
...next day I did a copy-action on a similar (maybe slightly faster)
PC (my own), and the copying needed about 30 minutes.
I don't know how much faster my DVD-drive was, but to mee it seems
that the installation (many head repositionings) together
with the scripts, that run, take so much more time.
But I had to test this in more detail to be sure, where
the bottleneck is (or where all bottlenecks are).

See above: alphabetical organization of the DVD-image.
But there were more suggestions and I have to reread the thread
and gather all ideas.

It will:


    Objective Caml is the most popular variant of the Caml language.
    From a language standpoint, it extends the core Caml language with
    a fully-fledged object-oriented layer, as well as a powerful module
    system, all connected by a sound, polymorphic type system featuring
    type inference.

    The Objective Caml system is an industrial-strength implementation of
    this language, featuring a high-performance native-code compiler
    (ocamlopt) for 9 processor architectures (IA32, PowerPC, AMD64, Alpha,
    Sparc, Mips, IA64, HPPA, StrongArm), as well as a bytecode compiler
    (ocamlc) and an interactive read-eval-print loop (ocaml) for quick
    development and portability. The Objective Caml distribution includes
    a comprehensive standard library, a replay debugger (ocamldebug),
    lexer (ocamllex) and parser (ocamlyacc) generators, a pre-processor
    pretty-printer (camlp4) and a documentation generator (ocamldoc).

for details.

If you miss something, please let me know.

There could be bytecode provided.
But possibly also native code.

See Win32-Release-Notes:

As there are not many OCaml-progarmmers out there, I know that
I might be solely wanting OCaml to be used.

But the reason I would prefer OCaml over any other language is
it's powerfulness.

When I switched from C to Perl, I had the feeling of: "why should
I ever again use C?". And there were rare cases, when I preferred
C over Perl. But these cases were rare.
When I switched from OCaml to Perl, at least after I was used to it,
it really was ugly to use Perl.... not to mention C. ;-)

If there would be setup-files available for all platforms,
for which the TeX-Binaries are available also, then
there should be no problem, IMHO.

I thought this can help in better ordering the installation.
But maybe I missed some point here?

I the code can be written platform independent but be compiled
to native code for all platforms, this should also be an option?

So, you see, Perl is NOT available on Windows-platforms.

I would prefer OCaml before Perl, and Perl before Shell,
(and Shell before C. ;-))

But this are only ideas.

If the texlive-project's people all prefer Perl, no problem with this,
even if it hurts ;-)

I didn't want to start a Language-clash, I just wanted to offer
more than one possibility (hoping my favourite would also be
interesting for others;-)).

The much more crucial points are:
  - what installation procdure is planned for the future (how to do it)
  - how can bottlenecks be removed (anti-slow)
  - how can the installation made clear (anti-mess)
