docutils is the library that supports the format (restructuredtext) that
these docstrings are written in. It *may* (I haven't looked) contain
functionality to render as clean plain text.

Hi,
SciPy (and NumPy) docstrings are written with a special kind of mark up:
For example, the docstring for the russellrao distance function looks
like this:
'\nComputes the Russell-Rao dissimilarity between two boolean 1-D
arrays.\n\nThe Russell-Rao dissimilarity between two boolean 1-D
arrays, `u` and\n`v`, is defined as\n\n.. math::\n\n
\\frac{n - c_{TT}}\n {n}\n\nwhere :math:`c_{ij}` is the number of
occurrences of\n:math:`\\mathtt{u[k]} = i` and
:math:`\\mathtt{v[k]} = j` for\n:math:`k n`.\n\nParameters\n
--\nu : (N,) array_like, bool\nInput array.\n
v : (N,) array_like, bool\nInput array.\n\nReturns\n
---\nrussellrao : double\nThe Russell-Rao
dissimilarity between vectors `u` and `v`.\n\n'
What's the most efficient way to turn this into a format where you can
format it nicely as a matplotlib text object?
I tried:
fig = plt.figure()
ax = fig.add_subplot(111)
props = dict(boxstyle='round', facecolor='wheat', alpha=0.5)
textstr = dist_fcn.__doc__
textstr = textstr.replace('math:',' ')
textstr = textstr.replace('`', '$')
textstr = textstr.replace('\n\n where', '$\n\n where')
ax.text(0.05, 0.95, textstr, transform=ax.transAxes, fontsize=14,
verticalalignment='top', bbox=props)
Which does an 'ok' job, at best, since fractions aren't converted
properly. Is there a way to do it nicely short of using some
horrendous regular expressions?

Version control is standard for application code, but databases havent
caught up. So what steps can you take to put your SQL databases under
version control? Why should you start doing it? Read more to find out.
