These notes intend to help people working on the CVS versions of
Bison.

* Requirements

Only the sources are installed in the CVS repository (to ease the
maintenance, merges etc.), therefore you will have to get the latest
stable versions of the maintainer tools we depend upon, including:

- Automake <http://www.gnu.org/software/automake/>
- Autoconf <http://www.gnu.org/software/autoconf/>
- Flex <http://www.gnu.org/software/flex/>
- Gettext <http://www.gnu.org/software/gettext/>
- Gzip <http://www.gnu.org/software/gzip/>
- Tar <http://www.gnu.org/software/tar/>
- Wget <http://www.gnu.org/software/wget/>

As of this writing, the latest stable version of Gzip is 1.2.4 but we
suggest using test version 1.3.5 (or later, if one becomes available).

Valgrind <http://valgrind.org/> is also highly recommended, if
Valgrind supports your architecture.

Bison is written using Bison grammars, so there are bootstrapping
issues.  The bootstrap script attempts to discover when the C code
generated from the grammars is out of date, and to bootstrap with an
out-of-date version of the C code, but the process is not foolproof.
Also, you may run into similar problems yourself if you modify Bison.

Only building the initial full source tree will be a bit painful,
later, a plain `cvs update -P & make' should be sufficient.

* First CVS checkout

Obviously, if you are reading these notes, you did manage to check out
Bison from CVS.  For the records, you will find all the relevant
information on:

	http://savannah.gnu.org/cvs/?group_id=56

The next step is asking the installation of all the missing files:

	$ ./bootstrap

And there you are!  Just

	$ ./configure && make && make check

At this point, there should be no difference between your local copy,
and the CVS master copy:

	$ cvs diff

should output no difference.

Enjoy!
