Overview

This is the early prototype version of 'DashBoard II', a generic
configurable interface to KTL control systems.  DashBoard II
is based on Tcl/Tk with various extensions, including
W. Lupton's Ktcl.  DBII allows the user to configure a custom
'dashboard' for monitoring and controlling ACS, DCS, and
instrument functions.  Any dashboard design can be saved
and reloaded at a later time.

Keyword definitions and attributes are derived from the
authoritative Sybase database of FITS and KTL keywords.
However, DBII can reload saved keywords from an ASCII file,
reducing dependency on the database and improving startup
time.

The dashboard is constructed by associating meters of various
types with KTL keywords, then placing the meters on the
dashboard.  It runs in three distinct modes:

engr	the usual mode, where the user places meters at will
	on a canvas (this mode will probably become the only
	mode if megawidgets are implemented to handle the
	'obsr' looknfeel)
obsr	a mode suggested by D. Phillips, in which the meters
	are strictly gridded and keyword writes are done as
	one batch rather than on a meter-by-meter basis
fake	a test mode in which no actual KTL connections are
	made (can be used for design even when out of contact
	with traffic controller, etc.)
