 Hi,

 Is there any graphical tool that can be used de create a shell script? For
example this tool should be able to create a box representing a command, when
you click a certain button on this box you would be able to change the options
that are passed to the command. Most importantly, if a cammand has an output (a
file containing the result) one should be able to connect this output to the
input of another box. The tool will automatically generate a file name
(/tmp/foobar) that will contain the result of the first command. each box
should have an "execute" button that will launch the command with the proper
parameters, provided that all its inputs are uptodate.

 I understand that my question may soud strange. Let me explain in which
context this may be useful. We have a set of programs that can be applied to
images (like filters, for example) and we would enable the students to
creates (graphically) chains of filters and see the result (some commands
just display an image). We also want the students to change the parameters
of the different filters.

 The configuration of such a tool would be a file containing the name of
each command and a description of its parameters (along with the
type of each parameter and each output).

 If you know of some tool that fits this description, I would be happy to
hear from you. Thanks in advance.
