The =--stop-on-error= option will cause =ltlcross= to abort on the
first detected error. This include failure to start some translator,
read its output, or failure to passe the sanity checks. Timeouts are
allowed.

** =--save-bogus=FILENAME=
The =--save-bogus=FILENAME= will save any formula for which an error
was detected (either some translation failed, or some problem was
detected using the resulting automata) in =FILENAME=. Again, timeouts
are not considered to be errors, and therefore not reported in this
file.
The main use for this feature is in conjunction with =randltl='s
generation of random formulas. For instance the following command
will run the translators on an infinite number of formulas, saving
any problematic formula in =bugs.ltl=.
#+BEGIN_SRC sh :export code :eval no
randltl -n -1 --tree-size 10..25 a b c | ltlcross --save-bogus=bugs.ltl 'ltl2tgba --lbtt %f >%T' 'ltl3ba -f %s >%N'
#+END_SRC
You can periodically check the contents of =bugs.ltl=, and then run
=ltlcross= only on those formulas to look at the problems:
#+BEGIN_SRC sh :export code :eval no
ltlcross -F bugs.ltl 'ltl2tgba --lbtt %f >%T' 'ltl3ba -f %s >%N'

The =--no-check= option disables all sanity checks, and only use the supplied
