address@hidden Validation Hooks
+
+If there is a policy decision to make, Monotone defines certain hooks to
+allow a client to validate or reject certain behaviors.
+
address@hidden @code
address@hidden validate_commit_message (@var{message}, @var{changeset_text})
+
+This hook is called after the user has entered his/her commit message.
address@hidden is the commit message that the user has entered and 
address@hidden is the full text of the changes for this revision,
+which can be parsed with the parse_basic_io function. If the hook finds the
+commit message satisfactory, it can return @code{true, ""}. If it finds
+fault, then it can return @code{false, reason} where @var{reason} is the
+reason the message was rejected. By default, this hook rejects empty log
+messages.
