These notes intend to help people working on the CVS versions of
Bison.  Only the sources are installed in the CVS repository (to ease
the maintenance, merges etc.), therefore you will have to the
maintainer tools we depend upon:

- Automake 1.6 or 1.6.1
- Autoconf 2.53 or better
  (actually, CVS Autoconf provides a better autoreconf...
   http://www.lrde.epita.fr/~akim/download/autoconf-2.53a.tar.gz)
- Gettext 0.10.1

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:

	$ autoreconf -f -v -i

Unfortunately, this will change a few files that should not have been
replaced, so remove them, and ask for the original copies:

	$ rm Makefile.am configure.in m4/Makefile.am
	$ cvs update

(Hopefully, these steps will no longer be needed in the future.)
Because of these changes, running autoreconf a second, and last time,
is needed.  Pay attention that the options are different this time:

	$ autoreconf -v -f

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, except maybe the date in po/*.po files.

Enjoy!
