Oslo.Privsep requries pycparser, which does not support being loaded
into python programs where the source is not available for doc string
references. This is because one of the things that happens with
an optomized python, is the files are "pre-compiled" and doc strings
are removed.
This is unfortunate, but just means the TinyIPA images are slightly
larger, Testing shows this is approximately 5 MB.
