No, you don't need to know anything about doctests to use ohrrpgce.py,
it's a completely ordinary module.
Just import it. The changes to memmapped-fileformats are basically
deleting things that are now in ohrrpgce.py, and, at the start of the
file, ">>> from ohrrpgce import *".
The main feature of ohrrpgce.py is currently the dtypes[] dictionary.
typical usage from updated memmapped-fileformats.rst looks like this:
from ohrrpgce import *
# mmap is a trivial wrapper function defined by ohrrpgce.py.
veh = mmap ('viking.veh', dtypes['veh'])
As I've mentioned before, I plan to abstract this so you can create an
RPGFile instance and then access
files in a memmapped way by doing
veh = rpgfile['veh']
If you want to learn about doctests, as mentioned before 'nose'
(http://somethingaboutorange.com/mrl/projects/nose/) is a good tool
when used with the
'--with-doctest' option (either in the nose config or on the commandline).

Yeah, it says in the source that's OHR-inspired. I'd prefer a tree
iterator, and it's a bit more difficult to work
out a good simple convention for passing ordered trees.

Hehe. (I'm baffled. Is this to do with the fact that 'wait, and and
what?' is slightly less nonsensical than 'wait, but but what?'?)
