What kind of magic do I need to get python to talk to Excel xlsm file?

If that is the case, then it is just not worth it.  However, I am seeing it more as a poorly constructed sentence.

How about:

>> Requires numpy, dateutil, pytz, setuptools , 
and optionally:  
numexpr, bottleneck, scipy, matplotlib, pytables, lxml, xarray, blosc, snappy, brotlipy, backports.lzma, statsmodels, sqlalchemy, psycopg2, and whatnot.

Does it suggest that the first four are required and the rest are optional?
Even then, it is still ambiguous.

It means you need all those things installed before you can install Pandas.
