val create : ?buffered:bool -> ?sync:sync_behaviour option -> ?lock:bool -> string -> t

create ?buffered ?sync ?lock path constructs a configuration referencing the file stored at path.

val to_string : t -> string

Marshal a config into a string of the form file://<path>?sync=(0|1)&buffered=(0|1)

val of_string : string -> ( t, [ `Msg of string ] ) Pervasives.result

Parse the result of a previous to_string invocation
