 The system time of the storage server must be correct to within 15 minutes
 in order for S3 to accept the authentication provided with requests.

+DevPay
+======
+
+Optionally, Amazon `DevPay`_ may be used to delegate billing for a service
+based on Tahoe-LAFS and S3 to Amazon.
+
+If DevPay is to be used, the user token (in base64 form) must be stored in
+the file ``private/s3usertoken``. DevPay-related request headers will be
+sent only if this file is present when the server is started. Each combination
+of user and DevPay product has a unique user token, so this token implies the
+product, and therefore the billing structure. It is currently assumed that
+only one user token is needed by a given storage server.

[mutable/retrieve: don't write() after we've been pauseProducer'ed
Brian Warner <warner@lothar.com>**20111017002400
 Ignore-this: 417880ec53285c4887f8080e1ddeedc8
 
 This fixes a test failure found against current Twisted trunk in
 test_mutable.Filenode.test_retrieve_producer_mdmf (when it uses
 PausingAndStoppingConsumer). There must be some sort of race: I could
 make it fail against Twisted-11.0 if I just increased the 0.5s delay in
 test_download.PausingAndStoppingConsumer to about 0.6s, and could make
 Twisted-trunk pass by reducing it to about 0.3s .
 
 I fixed the test (as opposed to the bug) by replacing the delay with a
 simple reliable eventually(), and adding extra asserts to fail the test
 if the consumer's write() method is called while the producer is
 supposed to be paused
 
 The bug itself was that mutable.retrieve.Retrieve wasn't checking the
 "stopped" flag after resuming from a pause, and thus delivered one
 segment to a consumer that wasn't expecting it. I split out
 stopped-flag-checking to separate function, which is now called
 immediately after _check_for_paused(). I also cleaned up some Deferred
 usage and whitespace.

 The filecaps used to be produced with hints for 'k' and segsize, but they
 weren't actually used, and doing so had the potential to limit how we change
 those filecaps in the future. Also the parsing code had some problems dealing
 with other numbers of extensions. Removing the existing fields and making the
 parser tolerate (and ignore) extra ones makes MDMF more future-proof.
