Hi Paul,

You are right, having all the metadata on a separate README file is
really important; I know people not even putting the column names in
the data files to be sure users read the README.
But I also think having the metadata inside the data file is useful as
a reminder when working with the data.

Concerning the column descriptions in FITS files, pyfits /
astropy.io.fits does not handle them, but it is always possible to add
the TCOMM keywords manually to the HDU headers.
