[IPython-dev] How to preconfigure notebook environment in v1.1?

[Adam Sadovsky]

For the record, I ended up achieving this by modifying KernelManager to
invoke the original script in a subprocess (rather than just calling zmq
main), and then configuring that binary, when called in kernel mode (i.e.
with "kernel" argument), to call IPython.start_kernel with the desired
user_ns passed in.

Is there any documentation for developers who want to better understand the
internal IPython APIs, specifically around kernels, applications, etc.? I
felt myself digging around somewhat blindly in order to figure this out,
and I'm sure there are better ways to do it (that don't require modifying
IPython internals).
