------------------------------------------------------------------

This is a pdp extension lib that contains modules for cellular
automata built on a (very) minimal forth-like virtual system
(scaf - simple cellular automaton forth) to define update rules. a 
compiler is included to produce scafo object code that can be 
dynamically loaded into the pdp_ca module. so it is possible to 
add/change rules without restarting pd (note however you need to close 
all lib files before the dynamic loader reloads the lib).  see 
scaf/README for details.


pdp_ca2image and pdp_image2ca are included for conversion between
CA packets and image packets. (pdp_ca2image produces greyscale
images)

Have a look at the patches in test/ for some crude docs. The file
README.scaf contains some more info on the internals.


Requirements:

* pd
* pdp
* linux
* perl for the forth compiler
* an intel/amd processor that supports MMX


Building:

Edit Makefile.config to reflect your system settings. For now this 
should be the pd dir, the pdp dir and the pdp_scaf dir.

type "make" in the top directory. Remember to type "make clean all" 
after editing Makefile.config


Using:

add "-lib <SCAF_DIR>/pdp_scaf" to the pd command line after the 
"-lib <PDP_DIR>/pdp" part.



launch pd with the options -lib $PDP_DIR/pdp -path $PDP_DIR/abstractions

Directory structure:

include/	header files
pdp/		pdp external code
system/		forth system code
test/		some test patches (cryptic doc)
modules/	ca rule libraries



Please let me know if you discover a bug or think something doesn't work 
right. Code, documentation or example patches are more than welcome of 
course.

Have Fun,

Tom
