+The format of |Option| is the same as returned by |rclone config
+providers|. The question should be asked to the user and returned to
+rclone as the |--result| option along with the |--state| parameter.
+
+The keys of |Option| are used as follows:
+
+- |Name| - name of variable - show to user
+- |Help| - help text. Hard wrapped at 80 chars. Any URLs should be clicky.
+- |Default| - default value - return this if the user just wants the default.
+- |Examples| - the user should be able to choose one of these
+- |Required| - the value should be non-empty
+- |IsPassword| - the value is a password and should be edited as such
+- |Type| - type of value, eg |bool|, |string|, |int| and others
+- |Exclusive| - if set no free-form entry allowed only the |Examples|
+- Irrelevant keys |Provider|, |ShortOpt|, |Hide|, |NoPrefix|, |Advanced|
+
+If |Error| is set then it should be shown to the user at the same
+time as the question.
+
+    rclone config update name --continue --state "*oauth-islocal,teamdrive,," --result "true"
+
+Note that when using |--continue| all passwords should be passed in
+the clear (not obscured). Any default config values should be passed
+in with each invocation of |--continue|.
+
+At the end of the non interactive process, rclone will return a result
+with |State| as empty string.
+
+If |--all| is passed then rclone will ask all the config questions,
+not just the post config questions. Any parameters are used as
+defaults for questions as usual.
+
+Note that |bin/config.py| in the rclone source implements this protocol
+as a readable demonstration.

 you would do:
