+\fBwaits\-for.d\fR = \fIdirectory-path\fR
+For each file name in \fIdirectory-path\fR which does not begin with a dot,
+add a \fBwaits-for\fR dependency to the service with the same name. Note that
+contents of files in the specified directory are not significant; expected
+usage is to have symbolic links to the associated service description files,
+but this is not required. Failure to read the directory contents, or to find
+any of the services named within, is not considered fatal.
+
+The directory path, if not absolute, is relative to the directory containing
+the service description file.
