[gnugo-devel] multi-board branch

[Paul Pogonyshev]

I have created a new CVS branch tagged `multi-board'.  It currently
differs from the the trunk only in files that are the sources for
`libboard.a'.

Basically, `libboard.a' is now completely switched to using a `Goban'
object and it compiles fine.  I have no idea if it works.  I'd bet
that there are a few bugs, because there are changes _everywhere_ in
`board.c'.

The interface for creating new `Goban' objects is very minimalistic at
present and consists of a single create_goban() function.  It is not
used anywhere yet.

I decided to break private `Goban' data out into a separate structure,
obviously called `Goban_private_data'.  There were two goals: firstly,
to explicitly mark private data as such (you cannot access them unless
you include new header `board-private.h', which you should not), and
secondly, to allow proper constification of `board.c' functions
arguments (many functions that merely retrieve information have to
alter internals for that purpose.)

So far I ask everybody not to make any changes in the branch and
preferably no changes to the board code in the trunk.  Comments and
suggestions, on the other hand, are welcome.
