gr.bytes_to_syms is the SWIG generated wrapper for gr_bytes_to_syms.
The interface exported to Python is in gr_bytes_to_syms.i

As you've probably figured out by now, the gr_simple_framer.cc is very
simple.  It just sticks a 4 byte Barker code (actually, I think we
just made up a random number because when we wrote this we were
sitting in a hotel room) at the beginning, followed by a 1 byte
sequence number and an unused zero byte.

Feel free to come up with better / more flexible encapsulator and
corresponding deencapsulator.  I'd be delighted to add it to the code base.
