* README: Typo.
* HACKING: s/CVS/GIT/ and add some tricks about libtool and doxygen.

* NEWS: Update for upcoming 0.5.
* HACKING: Update Automake requirement.
* README: Mention the mailing list.
* bench/ltlcounter/README: More text.
* configure.ac: Report bugs to spot@lrde.epita.fr.

add an AC_CONFIG_MACRO_DIR call.
* m4/libtool.m4, tools/ltmain.sh: Remove.

* HACKING: Mention that we require Bison >= 2.4 for developers.
* src/evtgbaparse/evtgbaparse.yy, src/tgbaparse/tgbaparse.yy,
src/ltlparse/ltlparse.yy: The sections "%{ ... %}" should now be
renamed "%code requires { ... }" or "%code { ... }" depending on
whether they should end up in the parser's header file or its cc
file.  Also use %language, %locations, %defines, instead of
command-line arguments.
* src/evtgbaparse/Makefile.am, src/tgbaparse/Makefile.am,
src/ltlparse/Makefile.am: Remove the --locations, --defines
and --languages in the call to bison.  Add -Wall -Werror to
catch more errors.
Thanks to Akim Demaille <akim@lrde.epita.fr> for the help.

Debian versions installed in build hosts during automatic builds.

* m4/libtool.m4: New file, from GNU Libtool 1.4.24.

to Bison 2.0.

* src/sanity/80columns.test, src/sanity/style.test: Process *.hxx files.
* src/tgbaalgos/ndfs_result.hh: Rename as ..
* src/tgbaalgos/ndfs_result.hxx: ... this, so it does not get
documented (and so Doxygen do not complain).
* src/tgbaalgos/magic.cc, src/tgbaalgos/se05.cc, src/tgbaalgos/tau03.cc,
src/tgbaalgos/tau03opt.cc: Adjust include.
* src/tgbaalgos/Makefile.am: Rename ndfs_result.hh as ndfs_result.hxx
and do not install it, this is a private header.

DOT_MULTI_TARGETS, and disable GROUP_GRAPH (it causes segfault).
* src/tgbaparse/public.hh (format_tgba_parse_errors): Complete
Doxygen comment.

Compiling the runtime in a separate modules is no longer required,
and actually it does not work anymore...
* wrap/python/swigpy.i: Remove.
* wrap/python/Makefile.am (_swigpy.la): Remove all references.
($(srcdir)/spot_wrap.cxx, $(srcdir)/buddy_wrap.cxx): Do not
use -noruntime.
