My Gnuplot invocation Simple application invokation: User wants to run the application 'gnuplot' to produce a plotted graphical file based on some data shipped in from elsewhere (perhaps as part of a workflow). A front-end application will then build into an animation of spinning data. Front-end application knows URL for data file which must be stage in. Front-end application wants to stage in a control file that it specifies directly which directs gnuplot to produce the output files. In case of error, messages should be produced on stderr (also to be staged on completion) and no images are to be transferred. gnuplot /usr/local/bin/gnuplot control.txt input.dat output1.png 1.0 2097152.0 control.txt overwrite true http://foo.bar.com/~me/control.txt input.dat overwrite true http://foo.bar.com/~me/input.dat output1.png overwrite true rsync://spoolmachine/userdir
