File Class Editor

The File Class Editor selects the way in which this file type will be
recognised by the Opus 5 system.  The name field specifies the name of the
file, the ID is a shorthand way of expressing the filetype.  The Pri is the
priority of that file type, it should normally be set at 0.

The file identification definition can be altered with the add, insert and
remove gadgets.  The scripts consist of a group of match instructions linked
together with logical 'and's and 'or's.  For any more detail on the File
Class Editor please consult your Opus 5 manual.
