  <p>Ask the server for a hash of a section of this file.  This can be used
  to verify a successful upload or download, or for various rsync-like 
  operations.</p>
  <p>The file is hashed from <code>offset</code>, for <code>length</code> 
  bytes.  If <code>length</code> is 0, the remainder of the file is hashed.
  Thus, if both <code>offset</code> and <code>length</code> are zero, the 
  entire file is hashed.</p>
  <p>Normally, <code>block_size</code> will be 0 (the default), and this 
  method will return a byte string representing the requested hash (for 
  example, a string of length 16 for MD5, or 20 for SHA-1).  If a non-zero 
  <code>block_size</code> is given, each chunk of the file (from 
  <code>offset</code> to <code>offset + length</code>) of 
  <code>block_size</code> bytes is computed as a separate hash.  The hash 
  results are all concatenated and returned as a single string.</p>
  <p>For example, <code>check('sha1', 0, 1024, 512)</code> will return a 
  string of length 40.  The first 20 bytes will be the SHA-1 of the first 
  512 bytes of the file, and the last 20 bytes will be the SHA-1 of the 
  next 512 bytes.</p>
