Default pipeline?

If you run "make" without a make file, it looks for "Makefile".
If you run "ant" without a build file, it looks for "build.xml".

If you run an XProc processor without specifying a pipeline, should it
look for a default pipeline. What should it be called?

                                        Be seeing you,
                                          norm
