+SCHEDULING
+==========
+
+By default, each configuration file is processed everyday at 01:00 (1
+AM). This can be changed by specifying the 'when' option in a config
+file.
+
+For example:
+
+ when = sundays at 02:00
+ when = 30th at 22
+ when = 30 at 22:00
+ when = everyday at 01 <-- the default
+ when = Tuesday at 05:00
+
+A configuration file will be processed at the time(s) specified by the
+"when" option. If multiple "when" options are present, then they all
+apply. If two configurations files are scheduled to run in the same
+hour, then we fall back on the alphabetical ordering specified above.
+If two configurations files are scheduled close to one another in
+time, it is possible to have multiple copies of backupninja running if
+the first instance is not finished before the next one starts.
+
+These values for 'when' are equivalent:
+
+ when = tuesday at 05:30
+ when = TUESDAYS at 05
+
+These values for 'when' are invalid:
+
+ when = tuesday at 2am
+ when = tuesday at 2
+ when = tues at 02
