sounds perfect to me

not me

I wrote a prototype of a java based installer and am currently testing
it on different platforms. I'll post it as a patch to SF in a day or
two. Then we can discuss if that might be a way to go. Its not a
sparkling beauty, but IMHO it does its job on the installation side.
More soon.

I'm interested to help with a reproducible distribution in the short
term, and in simplifying java imports.

Then I'd like to help with an easy to use testing environment for unit
tests and bug tests. I would feel more confident in supplying patches
when I could run them against a whole bunch of existing tests before.

And in the longer term I am very interested in java integration stuff
(including the cluster you mentioned above).

Thanks, and best wishes,
Oti.

Do you mean like this?

Site access and content is primarily maintained by Sean McGrath at the 
moment.  I'm not sure I have access yet to jython.org so I need to work 
on that.  Establishing some sort of blog would be a good idea.

On this topic, we need to go through the bug list and see which ones 
still exist in CVS and close those we can.  I don't think the list has 
been maintained in a quite a long time.

thanks,

Can we get the boolean constants even with out the true boolean type
(the way that CPython 2.2.x did?).

This sounds great.  I think we should get this info up on the web site
as well -- Brian, who currently controls access to the web site? 
Again, I think something blog like that was updated with a status
every week or so would go a long way towards ending the "is Jython
alive" messages on this list.

I'm going to look through the code and bugs and see if there's
anything I'd be helpful at, but it might be a little bit before my
time opens up.

Here http://sf.net/mailarchive/forum.php?thread_id=6232893&forum_id=5586
I've been accidentally hit by a lack of PEP 293 implementation
(no suprise, it's new in 2.3) so I decided to implement it myself,
but Lib/test/test_codeccallbacks.py from Python 2.3.4 requires
unicodedata module (it uses it in one place only), which is in C and
has been introduced in Python 2.0 - so I'm a little uncertain now -
should  I translate unicodedata to Java and then get back to PEP 293 or
just leave it as is? Should Jython have unicodedata available? (I'm not
sure how much work is it, though, but I guess it's doable <wink>).
