1 FHX
	FHX is a program to list the file header for any file that
	has the header extended.
 
	Its primary use is to search the INDEX file for clobbered
	headers. DSC can bomb if it encounters bad headers but it
	will report the File ID of the extension file header, not
	the File ID of the primary file  header, and headers have
	no backward linkage to let one find the primary header.
