Command-line tools: Command-line tools:
* BACKWARD INCOMPATIBILE CHANGE: All tools that output automata now
use the HOA format by default instead of the GraphViz output.
This makes it easier to pipe several commands.
If you have an old script that relies on GraphViz being the default
output and that you do not want to update it, use
export SPOT_DEFAULT_FORMAT=dot
to get the old behavior back.
* Tools that output automata now accept -d as a shorthand for --dot. * Tools that output automata now accept -d as a shorthand for --dot.
