* src/bin/ltlcross.cc: Here.
* NEWS, THANKS: Update.

* configure.ac, NEWS, doc/org/tools.org: Bump version to 1.1.2.

* NEWS, configure.ac, doc/org/tools.org: Bump version.

* src/bin/ltlcross.cc: Implement the new option.  Average the product
statistics on all products.
* src/tgbatest/basimul.test, src/tgbatest/ltlcross.test,
src/tgbatest/ltlcross2.test, bench/ltl2tgba/tools: Use the new option.
* NEWS: Mention it.

* src/tgba/bdddict.cc, src/tgba/bdddict.hh
(unregister_all_typed_variables): New method.
* src/tgbaalgos/degen.cc (degeneralize): Use it.
* NEWS: Mention it.

* src/tgbaalgos/simulation.hh, src/tgbaalgos/simulation.cc
(simulation_sba, cosimulation_sba, iterated_simulations_sba): New
function.  Also speedup the existing functions by avoiding
add_acceptince_conditions() and add_conditions().  Finally, use
scc_filter_states() when dealing with degeneralized automata.
* src/tgbaalgos/postproc.cc, src/tgbaalgos/postproc.hh (do_ba_simul):
New method.  Use it after degeneralization.
* src/tgba/tgbaexplicit.hh (get_transition, get_state): New methods.
* src/tgbatest/basimul.test: New file.
* src/tgbatest/Makefile.am (TESTS): Add it.
* NEWS: Introduce the new function and summarize the bug.

* src/bin/common_finput.cc: Here.
* src/ltltest/ltlfilt.test: Test it.
* NEWS: Mention it.

* src/bin/ltlcross.cc: Here.
* NEWS: Mention it.

The main motivation is the upcoming patch that introduces
simulation_sba() and requires this function.

* src/tgbaalgos/sccfilter.hh, src/tgbaalgos/sccfilter.cc: Implement it.
* src/tgbaalgos/postproc.cc: Use it for monitors, because we do not
care about acceptance conditions.
* NEWS: Mention it.

* src/bin/ltlfilt.cc: Handle --universal and --eventual.  Match
only LTL formulas with --stutter-invariant.
* src/ltltest/ltlfilt.test: New file.
* src/ltltest/Makefile.am (TESTS): Add it.
* NEWS: Mention these bug fixes.

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.
* src/tgbatest/ltlcross2.test: Add a check with --lbtt --ba.
* NEWS: Update.

* src/bin/genltl.cc (R_n): Really generate (GFp1 || FGp2), not
(GFp1 || GFp2).
* NEWS: Mention the bug.
* THANKS: Update.

* configure.ac, doc/org/tools.org: Bump version number.
* NEWS: Likewise, plus some missing entries.

* src/bin/ltlcross.cc: Implement the counters.
* doc/org/ltlcross.org: Update the documentation.
* bench/ltl2tgba/sum.py: Do not assume a fixed column for the time.
* NEWS: Update.

* src/tgbaalgos/isweakscc.cc, src/tgbaalgos/isweakscc.hh: Do not pass
automata since they are known from the scc.  Avoid several dynamic
casts.  Try to match the established vocabulary wrt "weak" and
"inherently weak".  The old is_weak_scc() that used to enumerate cycles
is therefore renamed to is_inherently_weak_scc(), while the new
is_weak_scc() will should ensure all transitions are fully accepting.
* NEWS: Mention the new interface.

* src/bin/ltlfilt.cc: Add options --remove-x and --stutter-invariant.
* src/ltlvisit/remove_x.cc, src/ltlvisit/remove_x.hh: New files.
* src/ltlvisit/Makefile.am: Add them.
* src/ltltest/remove_x.test: New file.

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.

* NEWS, configure.ac: Bump version.

* src/ltlvisit/simplify.hh (ltl_simplifier_options): add
a boolean_to_isop option

* src/ltltest/isop.test: New file.
* src/ltltest/Makefile.am: Add it.
* NEWS: Mention it.

* NEWS, configure.ac: Bump version.

* src/misc/formater.cc, src/misc/formater.hh (scan): New method.
(prime): Use it.
* src/bin/ltlcross.cc (translator_runner::translator_runner): Scan each
specification string, and report those missing an input or output
%-sequence.
* NEWS: Mention it.

alphanumeric string that is not an operator.
* NEWS: Mention it.
* src/ltltest/lbt.test: New file.  Also tests previous patch.
* src/ltltest/Makefile.am: Add it.

* NEWS: Mention it.
* src/ltlvisit/lbt.cc: Instead of outputting a space after each
node, output one before each node but the first one.

* NEWS: Mention the fix.

GF(a|Xb) = GF(a|b)      GF(a|Fb) = GF(a|b)
FG(a&Xb) = FG(a&b)      FG(a&Gb) = FG(a&b)

* src/ltlvisit/simplify.cc: Implement them.
* NEWS, doc/tl/tl.tex: Document them.
* src/ltltest/reduccmp.test: Test then.
