Last update 8/25/93: Version 1.2
--------------------------------
Changes made to CPL  from the description given in the
technical-report 630.

1) After executing a divide "one of the daughter cells" continues to
execute the instructions in the state. The other daughter cell does
not execute until the next time step.

2) All reserved words changed to lower case, use for_each_neighbor_do
and "with_neighbor_in_direction" instead of "for each neighbor do" and
"with neighbor in direction."

Known bugs
---------

1) Minor variations are observed in cell's area when they are
divided or grown.

2) Difficult to grow cells when they start with unit area. To be
precise you cannot grow a cell if all its neighbors have unit area. 

3) Will not accept comments on the same line as a #define.

Bugs Fixed
