+$details = "The .MUST_MAKE target variable is expanded when make is deciding
+whether a file needs to be made or not.  If it returns a non-empty string,
+when stripped, it will force the file to be made.  If it returns an empty
+string GNU make decides the normal way.  Note that .MUST_MAKE does NOT have
+to be expanded if make already knows the file needs building.  Also, note
+that for multi target rules it may be invoked for each file.";
