+Pure Data Packet
+
+Introduction
+
+PDP is an extension library for
+Pure
+Data,
+aimed at providing video and other media processing fuctionality.
+That's still it's main purpose, but as of version 0.13, there is more.
+PDP turned into a tool for writing PDP. See the section on
+Packet Forth.
+
+
PDP runs on Linux and OSX. The OSX version depends on Fink.
+
+
PDP's focus is on images and video, but there is no reason it
+should stay like that. There is support for matrix processing,
+1D and 2D binary cellular automata, opengl rendering (like Gem),
+scheme scripting (guile), ascii packets, bit grids, ...
+
+
For more image processing objects, streaming objects and a collection
+of very useful additions to the bare bones PDP functionality, have a look
+at Yves Degoyon's PiDiP library.
+
+
Since version 0.13.x, which is a merger between stable (0.12.x) and
+packet forth, PDP has been split up into 3 parts:
+
+
libtile - A lowlevel library for platform specific (integer, mmx, altivec)
+image processing operations and cache optimizations.
+ libpdp - The packet managing library + pf scripting language.
+ pdp - This is the stable pdp 0.12.x with support for packet forth.
+
+
+
+PDP for Pure Data
+
+This is considered to be the stable part of pdp. It has been stable since 0.12.x
+It has it's bugs & drawbacks & oversimplifications but will mostly stay
+like it is.
+
+It is optimized for intel/mmx and uses a 16bit signed yuv format ideal for real
+time video processing, mixing, blending and feedback. The pf layer is accessible
+from pd/pdp. The result of this is that you can write pdp objects in pf, or directly
+map pf operations to pdp objects.
+
+A 'getting started' documentation for pd/pdp/pidip is being worked on.
+Until then you can have a look at the 'pdp' subdirectory in pd's 'Pure Documentation'.
+Most objects are documented with pd style help patches accessible by right clicking
+on an object. The place to send questions is the pd mailing list. Bugreports can
+be sent to the pd list or me: pdp TA zzz TOD kotnet TOD org .
+
+
+
+Packet Forth
+
+The libpdp library is a C support library for media processing. It implements
+a mime-like media type system (packets), type conversion and packet operations,
+interface logic to connect pf to other applications, and other things you might
+need to write small 'scratch' media applications.
+
+All operations are implemented as extensions to a forth-like glue language
+called Packet Forth. For more information on this see the documentation
+in the libpdp distribution, or the mailing list archives.
+
+
+
+
+CVS
+
+The latest stable pdp release is 0.12.4.
+Because 0.13.x is still in a flux, the preferred way of accessing the code is CVS.
+You can access the modules in this way:
+
+
+export CVSROOT=:pserver:anonymous@zwizwa.fartit.com:/usr/local/cvsroot
+cvs login
+cvs co libtile
+cvs co libpdp
+cvs co pdp
+
+
+
To update, simply cd to each of the 3 directories, and type cvs update -d.
+
+
+
When extracting from cvs, you need to run the ./bootstrap script to
+create the configure scripts and build and install the packages in the order above.
+In order to compile pdp with libpdp (pf) support, you need to add a
+--enable-pf option when invoking pdp's configure script.
