* src/tgbaalgos/dotty.hh (dotty_reachable): Take a new
assume_sba argument.
* src/tgbaalgos/dotty.cc (dotty_bfs): Take a new
mark_accepting_states arguments.
(dotty_bfs::process_state): Check if a state is accepting using
the state_is_accepting() method for tgba_sba_proxies, or by
looking at the first outgoing transition of the state. Pass
the result to the dectorator.
(dotty_reachable): Adjust function.
* src/tgbaalgos/dottydec.hh, src/tgbaalgos/dottydec.cc,
src/tgbaalgos/rundotdec.hh, src/tgbaalgos/rundotdec.cc
(state_decl): Add an "accepting" argument, and use it to
decorate accepting states with a double border.
* src/tgbatest/ltl2tgba.cc: Keep track of whether the output
is an SBA or not, so that we can tell it to dotty().
* wrap/python/ajax/spot.in: Likewise.
* wrap/python/cgi-bin/ltl2tgba.in: Likewise.
* src/tgba/tgbaexplicit.cc (tgba_explicit::compute_support_conditions):
Fix logic. This function has always been returning bddtrue instead
of the actual computed value...
* wrap/python/tests/run.in, iface/nips/nipstest/defs.in,
iface/gspn/defs.in: Do not disable VERBOSE when running from "make
check". Since we have started using parallel-check on 2009-08-31,
we should always send verbose output to the log.
* src/tgbatest/kv.test, iface/nips/nipstest/dotty.test: Don't rely
on the ${DOT-...} syntax, because DOT is always set and might be
set to the empty value.
access to that host.
* src/tgbatest/kv.test: Use ${DOT-true} instead of ${DOT-:}. I
don't know, the MacOS shell must be mixing the syntaxes for
${DOT:-} and ${DOT-:}.
* iface/nips/nipstest/dotty.test: Likewise
* src/tgbaalgos/sccfilter.cc (scc_filter): If the input automaton
is an instance of tgba_explicit_number, create a similar automaton
for output, instead of a tgba_explicit_string.
* wrap/python/ajax/spot.in: Do full scc_filter for TGBA (-R3f),
and keep some extra acceptance conditions (-R3) when
degeneralizing. The converse was done.
* src/tgbaalgos/stats.hh (tgba_sub_statistics): New class.
(sub_stats_reachable): New function.
* src/tgbaalgos/stats.cc (sub_stats_bfs): New class.
(tgba_sub_statistics::dump, sub_stats_reachable): New function.
* src/tgbatest/ltl2tgba.cc (-kt): New option.
* src/tgbatest/ltl2tgba.test: Use -kt.
So far all neverclaims encountered would use (!(x)), but the
files from the Büchi store do not.
* src/neverparse/neverclaimscan.ll: Accept ! in front of guard,
so that we can read Promela files from Goal's Büchi store.
* src/tgbatest/neverclaimread.test: Test it.
* src/ltlparse/ltlscan.ll: Recognize ~, -->, and <--> operators
from Goal, to ease the use of formulas provided by the Goal team.
* src/ltltest/equals.test: Use these once, just to be on the
safe side.
* src/tgbaalgos/minimize.cc (minimize_monitor): Fix typo yielding
incorrect monitor if the input tgba is not deterministic.
* src/tgbatest/ltl2tgba.test: Add test case.
implement is_safety_mwdba().
Note: I swapped the name of safety and guarantee when I
implemented is_safety_automaton() on 2010-03-20. Fortunately,
is_safety_automaton() was only used where is_guarantee_automaton()
would have been correct.
* src/tgbaalgos/safety.cc (is_guarantee_automaton): Rename as ...
(is_guarantee_automaton): ... this.
(is_safety_mwdba): New function.
* src/tgbaalgos/safety.hh: Adjust and add documentation.
* src/tgbaalgos/minimize.cc: Use is_guarantee_automaton() instead
of is_safety_automaton().
* src/tgbatests/safety.test: Rename as ...
* src/tgbatests/obligation.test: ... this, and augment the
test.
* src/tgbatest/Makefile.am: Adjust.
* src/tgbatest/ltl2tgba.cc (-O): Display whether a formula
represent a safety, guarantee, or obligation property.
* NEWS: Adjust.

src/tgbaalgos/scc.cc, src/tgbaalgos/scc.hh: Update comments
to say that we "destroy" a state instead of "deleting" it.
Right now, destroy() just executes "delete this". But in a later
version, we will rewrite tgba_explicit so that it does not
allocate new states (and the destroy() method for explicit state
will do nothing).
* src/tgba/state.hh (state::destroy): New method, to replace
state::~state() in the future.
(shared_state_deleter): New function.

* src/saba/sabacomplementtgba.cc, src/tgba/tgbakvcomplement.cc:
Pass shared_state_deleter to the shared_ptr constructor, so that
it calls destroy() instead of delete.
* wrap/python/ajax/ltl2tgba.html: Remove the auto-update button, and
enable auto-update automatically after the first submission. Add
tools tips for the "Desired Output" tabs, and the Spot logo.
Add a email icon to encourage feedback.
* wrap/python/ajax/ltl2tgba.css: fix sizes of formula field and
send button. Set position of mail icon.

function does not get compiled.
* src/eltlparse/Makefile.am (AM_CPPFLAGS): Likewise.
(AM_CXXFLAGS): Also enable warnings.
* src/eltlparse/eltlparse.yy: Move helper functions from
the "%code requires" block to the "%code" block, so that they
do not appear in the eltlparse.hh file (which is included in
two places...).
* iface/nips/nips.cc (search_error_callback_assert): Comment
this unused function.
