12   -h
13          Print the command usage.
14
15   -H
16          Print the hybrid image computation set command usage.
17
18   Set  parameters:  The  hybrid  image computation options are specified
19   with the set command.
20
21   hybrid_mode <mode>
22          Specify a mode how to start hybrid computation.
23
24          mode must be one of the following:
25
26          0  :  start  with only transition function and build transition
27          relation on demand
28
29          1 : start with both transition function and relation (default)
30
31          2  :  start  with  only transition relation. Only this mode can
32          deal with nondeterminism.
33
