	Get rid of externals annoyances by getting argp from gnulib, the way
	it should be done. It may be useful to use gnulib for other things
	too; in particular, current gnulib has just introduced complexity
	metrics and coverage checks.

	N.B. Only developers who wish to change the gnulib setup need to
	install gnulib; all the necessary files for compilation are in
	Subversion.

	Care is required when deciding what files should be checked in and
	which ignored, as gnulib does not (yet) support Subversion. Git users
	will be happy, as they are automatically catered for. I used a simple
	technique: before updating the gnulib settings, I removed the gnulib
	and m4 directories, and then I added to Subversion all the files that
	gnulib created.

	Also, note that because we already use lib/ for the Vaucanson libraries,
	gnulib-tool needs to be invoked with --source-base=gnulib, which is
	where it stores its source files.

	Implementation of internal pipe in taf-kit (See Ticket #93):
	Commands can be sequenced using "\|" in tak-kit binaries.
	Command-line options are specific to their command except
	Timer & Bencher manipulation options (--report-time, --bench,
	--export-time-dot, --export-time-xml), which are global to
	the whole sequence.
	i.e.: --bench will benchmark the whole sequence.  The defect
	described in ticket #104 is also resolved.

	Note: In vcsn-b and vcsn-z, both automata and regular
	expressions keep their internal representation between
	commands.  In vcsn-tdc, both boolean automata and
	transducers do, but there might be issues about
	boolean_transducer namespace not being declared in
	CONTEXT_HEADER.
	The binaries have yet to be extensively tested.

	* src/common.hh,
	* src/main.cc:
	Add two command-line options to taf-kit binaries.
	The global timer in taf-kit can now be exported in
	DOT format using --export-time-dot and in XML format
	using --export-time-xml.

	Additionally, --report-time now takes the verbose
	level of the report as an optional parameter.

	See ../include/vaucanson/misc/timer.hh for
	documentation.

	* taf-kit/src/common.hh,
	* taf-kit/src/main.cc:
	Change global timer name from timer to global_timer to avoid
	conflicts with the new namespace.

	Former private classes of misc::Timer are now in the separate
	namespace misc::timer.  Minor changes are made to the taf-kit
	source to work with the new implementation.
	Documentation is provided in include/vaucanson/misc/timer.hh.

	Clean source code (thanks for pointing out what was wrong).
