[9fans] rc shell UNIX port repository

["Ciprian Dorin, Craciun" <ciprian.craciun@gmail.com>]

    Hello all!

    I'm a new (1 week) user of the rc shell (I want to migrate from
the Sh/Bash and their offsprings to rc after a lot of pain and misery
with them). :) And so far I like the rc look-and-feel (by look I mean
syntax and by feel I mean semantics.) as their quite minimal and with
just the right functionality. :)

    So back to the point: I'm using rc-1.7.1 UNIX port of the rc
shell, downloaded from:
        http://www.libra-aries-books.co.uk/software/download/rc/rc-1.7.1.tar.gz
    and during my initial trials, I've found quite a few bugs related
with the `-e` (exit shell on non-0 exit code), which I've tried (and
think I've managed) to solve.

    Now I'm trying to contribute back to the community, and I've sent
an email to Tig Goodwin (at tjg@star.le.ac.uk), which the mail server
rejected (it seems that the email is not valid any more). Then I've
sent an email to Byron Rakitzis (at byron@netapp.com), which worked
but no reply yet (maybe I'm on the to-do list. :) )
    So my questions are:
     * who is maintaining the UNIX port of rc shell? (is it still
Tig?) (if so what's the email address?)
     * is there a development repository for the source code?
     * is there a mailing list dedicated to the rc shell? (either
native or UNIX ported one?)
     * are there any unit-tests available for the rc shell? (because I
want to test my patches of not breaking something;)

    Thanks,
    Ciprian.

    P.S.: In my migration from Sh/Bash I've ended up deciding between
two candidates: scsh (Scheme Shell) (which is quite powerfull, being a
full R5RS Scheme implementation, with process management support, but
I've found a few rough edges (mainly related with error handling), and
it's quite heavy weight implementation with a large (in file number)
footprint), and rc (quite lightweight (only one executable statically
linked)).
    So are there any other worthy alternatives?
