To extract, compile, and link (under UNIX):

	% zcat skycal.tar | tar xf -
	% $cc skycalc.c -lm -o skycalc

where $cc is a C compiler.  Note that skycalc.c requires an ANSI c-compiler
as noted below.

REVISIONS -- 1994 September --- bug fix (V4.1)

Works around a problem with incorrect dates (all zeros) printed on
Silcon Graphics and perhaps others.

REVISIONS -- 1994 September version (V4)

The calendar-printing program is unchanged from V3.  The calculator
program is considerably revised; the most important revisions are:

1) Can read a file of objects; user can then set to coordinates
   of an object by name or have the object list sorted according
   to a number of different criteria.  Very useful while observing.
2) Can produce a log file of output results while running interactively.
   [N. B. -- This feature requires a working ANSI c-compiler; the standard 
   Sun "cc" compiler fails, and the ANSI version "acc" fails
   because of a known compiler bug.  However, the Open Software
   Foundation's "gcc" compiler *does* create working code for
   sparcstations.  A binary version is distributed for those who
   need it.]
