CHECKD is a program to check the filesystem and bittable for  consistent
data.   CHECKD  is  also  capable  of  rebuilding  the bittable from the
directory information and of scanning for  files  which  use  particular
disk addresses. Commands are in the general form:

	Keyword [optional arg] structure-name

Command			Description
-------			-----------

CHECK BITTABLE	Check the consistency of the bit table by comparing
		the pages marked as assigned against those pointed to
		by the file system. Also writes lost page addresses
		in a file.

CHECK DIRECTORY	Check just directory information on the specified
		structure.

LIMIT
UNLIMIT		Control whether directories may contain huge amounts
		of files or not.  Use LIMIT to guarantee that a
		particular structure can be used on small and large
		systems.  Use UNLIMIT to allow directories to grow
		large on a structure.  Note that if a directory grows
		large, the structure will no longer be usable on a
		small system.

REBUILD		Rebuild bittable from directory information on the
		specified structure.

RECONSTRUCT	Reconstucts the <ROOT-DIRECTORY> on the specified
		structure and then rebuilds the bit table.

CREATE		Accepts configuration information for a file
		structure and then creates a new file system on the
		specified units.

SCAN		Read a file o
