IPL may not be appropriate for us with new code, for instance those
working on the jbird jdbc driver moved to pure lgpl recently
(previouslty it was dual mpl + lgpl).

Currently for firebird code, Im working off a lgpl + exception clause
for new code I add:

http://firebird.sourceforge.net/rabbits/skywalker/fb_boilerplate.h

Unfortunately (or fortunately depending upon your point of view) I
mainly have worked in the build process, or changing existing code, so
it's not widespread.

However, within Firebird there is a mix of views, a number of the coders
who have worked in firebird prefer an lgpl approach. However Ann for
instance is a keen IPL/MPL supporter (as she says in the article).

The move to C++ generally was for bla-bla-bla C++ features :-). On my
part, mainly the OO stuff, which will hopefully help with reorganising
the code - and a code reformat to make it readable.

:-), It would work, but it *does* make the code hard to read.

Yes, Yaffil team tries to

I don't think we have the money (or the inclination) to go looking for
IPL violations (a lot will violate it quietly anyway) but watch out for
Borland, as someone pointed out to us, if you start making money they
are likely to come after you with a big stick. (mind you it's a long way
to Russia, so you could be safe :-).


In general im impressed the Russian fb/ib/yf community - book and all,
it is obviously quite mature and productive!

I agree, collaboration is the way to go.

Ouch, hope you make some sales soon.
