Subject: display error messages if calling __init__ or _del caused an
 exception updated docs compiler flag to exclude DSP objects pyext: fix for
 missing __init__ attribute some ASSERTs for explicitly created pyext classes
 (should be runtime checks i guess) let _inlets and _outlets default to 0

+You need to have Python installed on your system for the py/pyext external to work.
+For Windows pick an up-to-date package from http://www.python.org .
+For linux use the package manager. 
+For OS X keep things as the are - it has Python installed by default.
+
+
+The py/pyext package should run with Python version >= 2.1.
+It has been thoroughly tested with versions 2.2 to 2.4
+
+----------------------------------------------------------------------------
+
+Goals/features of the package:
+
+Access the flexibility of the python language in PD and MaxMSP
+
+
+PD - Load it as i library with e.g. "pd -lib py -path scripts"
+
+
+
+Check out the sample patches and scripts
+
+
+Description:
+
+With the py object you can load python modules and execute the functions therein.
+With the pyext you can use python classes to represent full-featured pd/Max message objects.
+Multithreading (detached methods) is supported for both objects.
+You can send messages to named objects or receive (with pyext) with Python methods.
+
+
+Known bugs:
+- The TCL/TK help patch is not usable under OSX.
+- With standard PD 0.37, threaded py scripts will cause "Stack overflows" under some circumstances
+  -> use PD 0.38 or the devel_0_37 cvs branch instead
+- It has been reported that pyext crashes on AMD64 with SSE enabled (for these CPUs, disable the respective compiler flags)
