 The identifer of a file (also called the "capability" to a file) is derived
 from two pieces of information when the file is uploaded: the content of the
-file and the upload node's "convergence secret". By default, the convergence
-secret is randomly generated by the node when it first starts up, then stored
-in the node's base directory (<Tahoe's node dir>/private/convergence) and
-re-used after that. So the same file content uploaded from the same node will
-always have the same cap. Uploading the file from a different node with a
-different convergence secret would result in a different cap—and in a second
