1) new OPAM command-line interface
Archive: <https://sympa.inria.fr/sympa/arc/caml-list/2012-12/msg00043.html>
------------------------------------------------------------------------
** Thomas Gazagnaire announced:

In order to prepare the beta release of OPAM (which should hopefully be 
announced at the end of next week if everything goes well), I've been working 
on improving its command-line interface (which is currently a bit had-hoc). 
Thanks to the great Daniel Bunzli's cmdliner[1] library, I now have a nice -- 
but incompatible -- command-line interface in the 'cmdliner' branch[2].

The main changes are:
* an uniform help interface, where all flags and parameters are correctly 
documents
* no more -long-option, only -s or --long
* 'opam remote' is still there for convenience but will be deprecated; use 
'opam repository' instead
* use of sub-sub-commands when necessary (ie. 'opam repository add')
* use non-ambiguous prefix of sub-command instead of the subcommand (ie. 
'opam repo' or 'opam rem')
* AND: a nice 'opam --help' and 'opam <subcommand> --help' output

I'm quite keen to get community feedback on this new command-line. Feel free 
to comment here, or to to use the issue tracker[3].

Cheers,
Thomas

** Tiphaine Turpin announced:

Sorry for spamming again on RTT (Run-time types for OCaml). This is just
to announce an online trying version (obtained by patching the Try OCaml
website). The current distribution (0.4) also improves the initial
release significantly.
