def formatbytes(sizeint, configdict=None, **configs):
"""
Given a file size as an integer, return a nicely formatted string that
represents the size. Has various options to control it's output.
You can pass in a dictionary of arguments or keyword arguments. Keyword
arguments override the dictionary and there are sensible defaults for options
you don't set.
Options and defaults are as follows :
* ``forcekb = False`` - If set this forces the output to be in terms
of kilobytes and bytes only.
* ``largestonly = True`` - If set, instead of outputting
``1 Mbytes, 307 Kbytes, 478 bytes`` it outputs using only the largest
denominator - e.g. ``1.3 Mbytes`` or ``17.2 Kbytes``
* ``kiloname = 'Kbytes'`` - The string to use for kilobytes
* ``meganame = 'Mbytes'`` - The string to use for Megabytes
* ``bytename = 'bytes'`` - The string to use for bytes
* ``nospace = True`` - If set it outputs ``1Mbytes, 307Kbytes``,
notice there is no space.
Example outputs : ::
19Mbytes, 75Kbytes, 255bytes
2Kbytes, 0bytes
23.8Mbytes
.. note::
It currently uses the plural form even for singular.
