+----------------------------------------------------------------------------
+
+VARIOUS NOTES:
+
+Platform specific:
+- PD does not allow signal and message to go into the same inlet (except leftmost inlet)
+- PD: with DSP objects all float messages to the leftmost inlet are converted to signal
+
+Restrictions in compatibility mode:
+- Max allows only 9 float/int inlets
+
+Porting to new compilers/platforms:
+- enums must be int-sized!!!
+- compiler must support bool type
+- an STL implementation must exist
+- C++ exceptions and RTTI must be enabled
+
+----------------------------------------------------------------------------
+
+KNOWN BUGS:
+- can't use MFC libraries because of global new and delete overloadings
+
+- MaxMSP Mach-O DSP externals cannot be the first externals loaded (e.g. in Max Runtime)
+ there must be a CFM signal external loaded beforehand!!! (Max will crash otherwise)
+ -> i think this is fixed in Max in the meantime!
+
+----------------------------------------------------------------------------
+
+TODO LIST:
+
+- optimizations for object initialization and messaging
+- SIMD for gcc
+
+- update documentation
+- add log messages for debugging version
+- use PD's t_float and t_int types (or comparable for 32-bit safety)
+
+- add double handlers
+- add signal in/out connection query function
+
+- support for Max qelem style
+
+- flext::post and flext::error should print via a worker thread (and should be unlimited in characters)
+
+- manage running threads individually (stop, isrunning?, priority etc.)
+
+----------------------------------------------------------------------------
+
+TESTS TO DO:
+
+- PD: problems with timed buffer redrawing (takes a lot of cpu time)
+- hard thread termination upon object destruction doesn't seem to work properly -> crash
+- Max rounding bug ... buffer resize could be one sample less!
+
+- PD: figure out what "pointer" messages do and whether they are correctly implemented in flext
+
+- Max buffer~ resize: flext_base::buffer::Frames(): must we use buffer or system sample rate?
+
+- check whether m_dsp gets called upon deletion of a used buffer (PD and MaxMSP may behave differently).
+ -> PD does call m_dsp, Max/MSP does not
