New in spot 1.0.2a (not released):
Several of the new features described below are discribed in

Křetínský, Jan Strejček: Compositional Approach to Suspension and
Other Improvements to LTL Translation. To appear in the
proceedings of SPIN'13.

latter one does not always have a positive effect, so it is

- A new translation, called compsusp(), for "Compositional
Suspension" is implemented on top of ltl_to_tgba_fm().
(See SPIN'13 paper.)
- Some experimental LTL rewriting rules that trie to gather
suspendable formulas are implemented and can be activated
with the favor_event_univ option of ltl_simplifier. As
always please check doc/tl/tl.tex for the list of rules.
* Command-line tools:
- ltl2tgba and ltl2tgta now honor a new --extra-options (or -x)
flag to fine-tune the algorithms used. The available options
are documented in the spot-x (7) manpage.

are documented in the spot-x (7) manpage. For instance use '-x
comp-susp' to use the afore-mentioned compositional suspension.
- The output format of 'ltlcross --json' has been changed slightly.
In a future version we will offer some reporting script that turn
