-CLI: Simulation Length
-----------------------
-
-If neither of the following two options are passed, the simulation runs as
-thought `-length 5000` was passed.
-
- - **`-random-length`**: A random length smaller than 10,000 generations but
- large enough to fill the screen is selected.
-
- - **`-length N`**: Request `N` generations be simulated on each run.
-
-Note that an upper limit of 10,000 generations is enforced in order to avoid
-`BadAlloc` errors from some X servers. For more details, read
-`WolframAutomata.c` starting around the comment, "The maximum number of
-generations is cell_size dependent. This is a soft limit and may be increased
-if ..."
