and adjust it to detect siPSL formulas, as in the paper of Dax et
al. (ATVA'09). For issue #51.
* src/ltlast/atomic_prop.cc, src/ltlast/binop.cc,
src/ltlast/bunop.cc, src/ltlast/constant.cc, src/ltlast/formula.cc,
src/ltlast/formula.hh, src/ltlast/multop.cc, src/ltlast/unop.cc: Rename
the property, and adjust its computation on siSERE.
* src/ltlvisit/remove_x.cc, src/ltlvisit/simplify.cc,
src/tgbaalgos/stutter.cc: Adjust to new names.
* src/bin/ltlfilt.cc: Add option --syntactic-sutter-invariant.
* src/ltltest/kind.test: Update tests and add some new.
Fixes#46.
* src/tgbaalgos/neverclaim.cc: Add option '6'.
* src/bin/common_aoutput.cc, src/bin/dstar2tgba.cc: Make it
possible to use the option.
* NEWS, doc/org/oaut.org: Document it.
* src/tgbatest/ltlcross2.test: Test it.
* src/tgbaalgos/sccinfo.cc, src/tgbaalgos/sccinfo.hh: add
scc_info::begin() and scc_info::end() methods to iterate over the
node_ vector. Tidy the scc_node structure that that its member
are accessed via methods.
* src/tgbaalgos/safety.cc, src/bin/ltlcross.cc: Simplify using
this interface.
Combined with 87c2b29, this fixes#7.
* src/tgbaalgos/stutterize.cc: Call keep_props().
* src/tgbaalgos/closure.cc: Just specify the encoding.
* src/bin/autfilt.cc: Add a --instut=2 option.
* src/tgbatest/stutter.test: More test.
* src/bin/ltl2tgba.cc, src/bin/randaut.cc: Catch exceptions
in main loop.
* src/tgbatest/ltl2tgba.test, src/tgbatest/randaut.test: Test
errors with unknown --dot argument.

support three kind of statistics printer, depending on whether the
tool input formulas, automata, or nothing.
* src/bin/randaut.cc, src/bin/autfilt.cc: Adjust.
* src/bin/ltl2tgba.cc: Use the common_aoutput printers. The
--csv-escape option disappeared along the way, but it was not honored
anyway...
* src/bin/autfilt.cc: Also accept '-u' for '--uniq'.
* src/bin/randaut.cc: Likewise, plus fix the unicity check.
* src/tgbatest/uniq.test: Really test it.
* src/tgbaalgos/dotty.cc, src/tgbaalgos/dotty.hh: Add an options
parameter.
* src/bin/randaut.cc, src/bin/autfilt.cc, src/bin/dstar2tgba.cc,
src/bin/ltl2tgba.cc, wrap/python/ajax/spot.in: Use it.

src/tgbatest/ltl2tgba.cc, src/tgbatest/monitor.test,
src/tgbatest/neverclaimread.test, src/tgbatest/tgbaread.test,

because automata are now output horizontally.
* NEWS: Mention the change.
* src/bin/autfilt.cc: Use isomorphism_checker.
* src/tgbaalgos/are_isomorphic.cc, src/tgbaalgos/are_isomorphic.hh: Wrap
are_isomorphic inside a class to keep the canonic version of the first
automaton between two calls, and use a more efficient algorithm in case
both automata are deterministic.
* src/tgbatest/isomorph.test: Add tests for deterministic automata.
* src/tgbaalgos/are_isomorphic.cc, src/tgbaalgos/are_isomorphic.hh,
src/bin/autfilt.cc: are_isomorphic now uses canonicalize. It returns a
bool, because the mapping cannot be deduced easily from the
canonicalized automaton.

for easy comparison of transition vectors.
* src/tgba/tgbagraph.hh: Add equality operator to tgba_graph_trans_data
and to tgba_digraph.

quiet_output.
* bench/dtgbasat/prepare.sh: Rename -q to --ignore-errors..
* src/ltltest/remove_x.test: Use -q.
* NEWS: Mention this change.
* src/bin/autfilt.cc: Do not use -I for --are-isomorphic.
Fix --help.
* src/tgbatest/isomorph.test: Adjust to use --are-isomorphic, and speed
it up 5-fold.
* src/bin/autfilt.cc: Return with exit code 1 if no match found.
* src/tgbaalgos/are_isomorphic.cc,src/tgbatest/degenlskip.test

src/tgbatest/explpro4.test,src/tgbatest/explprod.test
src/tgbatest/neverclaimread.test, src/tgbatest/readsave.test
src/tgbatest/tripprod.test: Use exit status to check for output
emptiness instead of 'test -n'.

* src/tgbatest/Makefile.am: Add it.
* src/tgba/tgba.hh, src/tgba/tgba.cc (set_named_prop): Add a template
version.
(get_named_prop): Hide the old version, and supply a template version
that casts.
* src/bin/ltlcross.cc, src/hoaparse/hoaparse.yy, src/tgbaalgos/hoa.cc,
src/tgbaalgos/product.cc: Adjust usage.
This way we can easily parse a stream of HOAs intermixed with
neverclaims.
* src/hoaparse/hoaparse.yy, src/hoaparse/hoascan.ll: Add rules
for neverclaims, adjusted from src/neverparse/neverclaimparse.yy
and src/neverparse/neverclaimparse.ll.
* src/hoaparse/public.hh, NEWS: Update documentation.
* src/neverparse/: Remove this directory.
* README, configure.ac, src/Makefile.am: Adjust accordingly.
