* NEWS: Mention it.

Rename the %S sequence as %c, for consistency with dstar2tgba.
* src/tgbatest/ltl2dstar.test: Add more tests.
* src/tgbatest/ltl2dstar2.test: New file.
* src/tgbatest/Makefile.am: Add it.

Provide a way to output automata with state-based acceptance.  Also
print the guards using to_lbt_string() for consistency: as a
consequence, atomic proposition that do not match p[0-9]+ are now
double-quoted.

* src/tgbaalgos/lbtt.hh (lbtt_reachable): Add a sba option.
* src/tgbaalgos/lbtt.cc: Implement it, and use to_lbt_string().
* src/ltlvisit/lbt.cc (is_pnum): Reject 'p' without number.
* src/bin/ltl2tgba.cc: Activate the sba option of --ba was given.
Add an option --lbtt=t to get the old behavior.
* src/bin/man/ltl2tgba.x: Document the LBTT format we use with
some links and examples.
* src/tgbatest/lbttparse.test: More tests.

This perform pre- and post-processings in addition to
the LTL-to-TGBA translation.

* src/tgbaalgos/translate.cc, src/tgbaalgos/translate.hh: New files.
* src/tgbaalgos/Makefile.am: Add them.
* src/tgbaalgos/postproc.hh: Make the private part protected, so
that we can inherit from that in the translator class.
* src/bin/ltl2tgba.cc: Use the translator class to hide LTL
simplification, translation, and postprocessings.
* NEWS: Mention it.

* src/bin/spot-x.cc, src/bin/man/spot-x.x: New files.
* src/bin/Makefile.am, src/bin/man/Makefile.am: Adjust.
* src/bin/man/ltl2tgba.x: Remove all fine-tuning options,
and make a reference spot spot-x (7).
* src/bin/common_setup.hh, src/bin/common_setup.cc: Add
a misc_argp_hidden version of the option, so that --help
and --version are not shown in the --help output used
by help2man to generate spot-x.7.
* src/bin/ltl2tgba.cc: Refer to spot-x.7.

* src/tgbaalgos/postproc.cc: Add an option_map parameter, and use to get
extra options to pass to the degeneralization algorithm.
* src/tgbaalgos/postproc.hh: Adjust prototype, and store Boolean
variables for degeneralize() options.
* src/bin/ltl2tgba.cc: Add a -x option to fill the option map, and pass
it to the postprocessor.
* src/bin/man/ltl2tgba.x: Document the three degeneralization options.

Enable LTL simplifications by default for ltl2tgba & ltl2tgta, and make
sure the ltl_simplifier_options are all false initially.  Before this
patch --low/-r1 had the same effect as --medium/-r2 with respect to LTL
simplification.

* src/bin/ltl2tgba.cc, src/bin/ltl2tgta.cc (simplification_level): Set
to 3 by default.

output option.
* src/bin/ltl2tgba.cc: Add a --monitor/-M option.
* NEWS: Mention monitors.
* src/tgba/tgbaexplicit.hh (is_accepting_state): Fix for the
case where the automaton has no acceptance set.

In particular, this get rid of the ugly -? option that argp adds by
default, and we also remove -V so that we can use it for something
else later.

* src/bin/common_setup.cc, src/bin/common_setup.hh (misc_argp):
Provide support for --help/--version/--usage output, replacing argp's
default builting version.
* src/bin/genltl.cc, src/bin/ltl2tgba.cc, src/bin/ltl2tgta.cc,
src/bin/ltlcheck.cc, src/bin/ltlfilt.cc, src/bin/randltl.cc:
Call argp_parse() with ARGP_NO_HELP, and use misc_argp instead.

* src/bin/ltl2tgba.cc, src/bin/ltl2tgta.cc: Destroy the translated
formulas.
* src/bin/ltlcheck.cc, src/bin/ltlfilt.cc: Free the unicity table on
exit.

* NEWS: Mention this.
* COPYING: Replace by GPL v3.
* src/sanity/style.test: Check files with the wrong license,
in case we forgot to update it during a merge.

Report error when writing to std::cout failed.  This is mainly
motivated by ltlfilt not being killed by SIGPIPE on lip6's OSX
buildfarm (SIGPIPE is probably ignored when the build is started), but
it could detect other errors such as a disk full.
