* wrap/python/tests/run.in: Make it easier to run python with gdb.
* wrap/python/tests/automata-io.ipynb: Add test case.
* wrap/python/spot.py (spot.automata): Make sure p is defined in all
cases.
* src/hoaparse/hoascan.ll: Make sure we do not close a file that
hasn't been opened.
Fixes#72.
* src/tgbaalgos/totgba.cc, src/tgbaalgos/totgba.hh: New files.
* src/tgbaalgos/Makefile.am: Add them.

a Generic output type, and call to_generalized_buchi() if
this type is not selected.

* src/bin/autfilt.cc: Add a --generic option, and set it
by default.
* src/taalgos/dotty.cc, src/taalgos/dotty.hh: Add an interface
similar to that of tgba/dotty.hh, even if we have to ignore
most options.
* src/taalgos/tgba2ta.cc, src/taalgos/tgba2ta.hh: Add an option
to display the intermediate automaton with explicit stuttering
transitions, for the purpose of making demonstrations.

to disable the "jump to the accepting level if the entering
state as an accepting self-loop" optimization.
* src/tgbaalgos/postproc.cc, src/tgbaalgos/postproc.hh: Check
the degen-lowinit option and pass it on to degeneralize().
* src/bin/spot-x.cc: Document it.
* src/tgbatest/degenlskip.test: Add some tests.
* src/tgbatest/ltl2ta.test: Update value. We output less
accepting states now.
Doing so is not wrong, but it's superfluous, and the extra accepting
state will cause additional work in emptiness checks based on NDFS.
Report from Jan Strejček.
* src/tgbaalgos/degen.cc: Here.
* src/tgbatest/degenid.test: Add a test case.
And add a cleanup_acceptance() version that copies.

and add the second version.

cleanup_acceptance_here.

pipes.

simplify a Boolean function with don't care.

src/hoaparse/hoaparse.yy (hoa_stream_parser::parse_strict): New method
that raises an exception whenever a syntax error is encountered.
* src/ltlparse/public.hh (parse_error): Move ...
* src/misc/common.hh: ... here.
* wrap/python/spot_impl.i: Wrap the hoa output.
* wrap/python/spot.py: Implement spot.automata.
* wrap/python/tests/automata-io.ipynb: New test.
* wrap/python/tests/Makefile.am: Add it.
This work around what appears to be an exception handling bug, causing
binaries to not always catch excepting thrown by the library.
* debian/rules: Here.
Fixes#70.
We don't modify the behavior of mask_keep_states(), because it is
actually useful in some algorithm to remove states without renumbering
all the other states.
* src/bin/autfilt.cc: Call purge_dead_states().
* src/tgbatest/maskkeep.test: Adjust.
* src/tgba/acc.cc, src/tgba/acc.hh: Add a way to extract
an unstatisfiable mark, and fix the eval() function for
Fin acceptance.

an unsatisfiable mark. Do not assume generalized Büchi.
* src/tgbatest/complete.test: New test.
* src/tgbatest/Makefile.am: Add it.
Sometimes, simplifying the acceptance condition (because it refers to
sets that do not appear in the automaton) cause more sets to be removed
from the acceptance condition, and therefore warrant another pass to
remove those sets from the automaton.
* src/tgbaalgos/cleanacc.cc: Here.
* src/tgbatest/hoaparse.test: Add a test case.
It makes more sense to assume that the removed set cannot be visited.
* src/tgbaalgos/mask.cc: Flip a Boolean.
* src/tgbatest/maskacc.test: Adjust test case.
* doc/org/autfilt.org: Add an example.
* src/tgba/tgbagraph.cc (purge_dead_states): Using a DFS to compute a
topological order, allowing to remove useless using a second
pass (instead of iterating the passes until there is nothing to remove).
* src/tgbaalgos/remfin.cc: Call purge_dead_states().
* src/tgbatest/remfin.test, src/tgbatest/det.test: Adjust expected
output.
* doc/org/autfilt.org: Update example.
... or the pointer might be invalidated if the environments
changes. Fixes#63.

Use Depends: ${source:Version} for libspot-dev. Fix description of
spot.

Fixes#62.
* src/tgbaalgos/dtbasat.cc, src/tgbaalgos/dtgbasat.cc: Add call to
prop_state_based_acc() when building an automaton with state-based
acceptance.

* doc/org/satmin.org: Update.
This implement several new options for --dot in order to
allow emptiness sets to be output as colored ⓿ or ❶...
Also add a SPOT_DOTDEFAULT environment variable.
* NEWS, src/bin/man/spot-x.x, src/bin/common_aoutput.cc,
src/bin/dstar2tgba.cc: Document the new options.
* doc/org/.dir-locals.el, doc/org/init.el.in: Setup
SPOT_DOTEXTRA and SPOT_DOTDEFAULT for all documents.
