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

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:

./configure
make
make install

If you don't have both libraries in the same dir and want to keep
it that way, hardcode the paths in Makefile.config.in and run 
configure. You need to do "make install" to install the scaf compiler 
"scafc" and the default ruleset. This is to be able to load plain 
(text) rule files and have the default rules loaded when you create
a pdp_ca object.

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
compiler/	forth system code
test/		some test patches (cryptic doc)
rules/		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
