doc/org/tut51.org: Adjust all dot outputs to produce svg.
* doc/org/arch.tex, doc/org/hierarchy.tex, doc/org/satmin.tex: Adjust
to produce a pdf with 12pt text.
* doc/Makefile.am: Adjust the generation of arch.svg, hierarchy.svg,
and satmin.svg: From above.
* doc/org/.dir-locals.el.in, doc/org/init.el.in: Adjust dot arguments
to produce svg with 12pt text (the default was 14pt).
* doc/org/spot.css: Use Lato as the main font for consistency with
automata.
* HACKING: pdf2svg is now required to build the doc.
For now, ltlsynt only handles LTL realizability. It uses a reduction to
parity game followed by Calude et al.'s reduction from parity game to
reachability game.
* bin/ltlsynt.cc, bin/Makefile.am, bin/man/ltlsynt.x,
bin/man/Makefile.am, bin/.gitignore: New binary.
* doc/org/arch.tex, doc/Makefile.am, doc/org/tools.org,
doc/org/ltlsynt.org: Document it.
* spot/misc/game.cc, spot/misc/game.hh, spot/misc/Makefile.am: Parity
game wrapper for parity automata + reachability game interface from
Calude et al.'s paper.
Fixes#254.
* spot/gen/formulas.cc, spot/gen/formulas.hh: New files.
* spot/gen/Makefile.am: Add them.
* spot/Makefile.am: Fix build order.
* bin/genltl.cc: Move most code to the above files and adjust.
* bin/Makefile.am: Link genltl with libspotgen.
* doc/org/arch.tex: Adjust picture to show that genltl uses
libspotgen.
* python/spot/gen.i: Include formulas.hh.
* tests/python/gen.py: Make sure genltl() and ltl_pattern_name()
can be called.
For #254.
* doc/org/arch.tex: Include libspotgen and its python bindings,
genaut, and also the buddy bindings.
* doc/org/concepts.org: Adjust the description.
