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:
'\n Computes the Russell-Rao dissimilarity between two boolean 1-D
arrays.\n\n The 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\n where :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\n Parameters\n ----------\n u : (N,)
array_like, bool\n Input array.\n v : (N,) array_like, bool\n
Input array.\n\n Returns\n -------\n russellrao : double\n
The 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
