+hurry.filesize
+==============
+
+hurry.filesize a simple Python library that can take a number of bytes and
+returns a human-readable string with the size in it, in kilobytes (K),
+megabytes (M), etc.
+
+The default system it uses is "traditional", where multipliers of 1024
+increase the unit size::
+
+  >>> from hurry.filesize import size
+  >>> size(1024)
+  '1K'
+
+An alternative, slightly more verbose system::
+
+  >>> from hurry.filesize import alternative
+  >>> size(1, system=alternative)
+  '1 byte'
+  >>> size(10, system=alternative)
+  '10 bytes'
+  >>> size(1024, system=alternative)
+  '1 KB'
+
+A verbose system::
+
+  >>> from hurry.filesize import verbose
+  >>> size(10, system=verbose)
+  '10 bytes'
+  >>> size(1024, system=verbose)
+  '1 kilobyte'
+  >>> size(2000, system=verbose)
+  '1 kilobyte'
+  >>> size(3000, system=verbose)
+  '2 kilobytes'
+  >>> size(1024 * 1024, system=verbose)
+  '1 megabyte'
+  >>> size(1024 * 1024 * 3, system=verbose)
+  '3 megabytes'
+
+You can also use the SI system, where multipliers of 1000 increase the unit
+size::
+
+  >>> from hurry.filesize import si
+  >>> size(1000, system=si)
+  '1K'
