 yes.  _their_ time - not mine.  the pyjamas project has always been
done on the basis that skilled software developers such as myself and
others ... how-to-say... "invite" other people to benefit from the
fact that they want to have tools which make _their_ lives easier.

 as we receive absolutely no money of any kind from any sponsor or
other free software organisation nor from any corporation, there _is_
no money to spend on doing the "usual" kind of free software project,
where the developers are paid / funded to deal with issues effectively
"for free".

 so instead i encourage and invite people to contribute, and some do,
and some don't: the end-result is the product of everyone's collective
input.

 at least _some_ input would be good!  the knowledge doesn't have to
be there: just the bugreports saying "there's a problem and here's
exactly how you reproduce it" would be a start!

 ... how?? there's a bugtracker, wiki, svn repository, over 30
examples and a developer list.  the code really _is_ very very small
(the UI widget set, with around 75 widgets, minus the license header
text is only around 4,000 lines _total_, making it very very simple
and very very easy for people to get used to).  suggestions welcome!

 yes. been there. didn't receive any return on investment. did some
projects. received about 25% of required money to pay bills.  need
£15k pa; receiving approximately £7-8k.

 thanks.  i fixed the lightout one, don't worry about that.

 that's reading text files using HTTPRequest (just like the Bookreader
and Slideshow examples), so there's no dependency like that.

 each of the examples, if it has dependencies such as django, it's
assumed that you know how to install and configure django, and there's
instructions in the README to set things up.

 hooray!  thank you!  a bugreport!  ok, that was a one line fix:

@@ -85,6 +85,6 @@ class Game(SimplePanel):
 if __name__ == '__main__':
     pyjd.setup("public/lightout.html")
     game = Game(3)
-    RootPanel().get('game').add(game)
+    RootPanel('game').add(game)

 so, don't worry about that one, it's done.  small change to the API
(to support something that someone else needed) had knock-on effects.

 thank you.  greatly appreciated.

 no problem, i understood that you weren't - i was just making it
clear that i know what's involved.

 be happy to help - on the pyjamas-dev list.  conversion has been
discussed numerous times, there.  i refer people to java2py each time,
so you could search the archives on that.

 thank you wolfgang.
