representation of the size of the data represented by this URI. All base32
encodings are expressed in lower-case, with the trailing '=' signs removed.

Where (writekey) is the base32 encoding of the 16-byte AES encryption key
that is used to encrypt the RSA private key, and (fingerprint) is the base32
encoded 32-byte SHA-256 hash of the RSA public key. For more details about

The format for mutable read-caps is::
The grid layer provides a mapping from URI to data. To turn this into a graph
of directories and files, the "vdrive" layer (which sits on top of the grid
layer) needs to keep track of "directory nodes", or "dirnodes" for short.
-docs/dirnodes.txt describes how these work.
+`docs/dirnodes.rst <../dirnodes.rst>`_ describes how these work.
Dirnodes are contained inside mutable files, and are thus simply a particular
way to interpret the contents of these files. As a result, a directory
