+
+An extended version of makesourceversions (which calls this function
+internally) that allows for multiple packages, architectures, and
+outputs warnings and debugging information to provided SCALARREFs or
+HANDLEs.
+
+The guess_source option determines whether the source package is
+guessed at if there is no obviously correct package. Things that use
+this function for non-transient output should set this to false,
+things that use it for transient output can set this to true.
+Currently it defaults to true, but that is not a sane option.
