Ideally, it's packaged in such a way that it's usable for scipy too --
at the moment it's used in scipy.sparse via Cython.Tempita + a
fallback to system installed tempita if Cython.Tempita is not
available (however I'm not sure that fallback is ever exercised).
Since scipy needs to support numpy down to 1.8.2, a vendorized copy
will not be usable for scipy for quite a while.

So, it'd be great to handle it like numpydoc: to have npy_tempita as a
small self-contained package with the repo under the numpy
organization and include it via a git submodule. Chuck, do you think
tempita would need much in terms of maintenance?

To put some money where my mouth is, I can offer to do some legwork
for packaging it up.
