CLIO - Command Language I/O.
This is the interface between IRAF applications and the IRAF command
language. To an application, the CL appears to be a database managing named
"psets" (parameter sets) containing parameters. CLIO is used by the
application to read and write these parameters. The parameter sets are
predefined at the CL level rather than being dynamically defined by the
application.
