; Any line beginning with a ';' is assumed to be a comment.  Any other
; non-blank line is assumed to be a possible JPL ephemeris file.  Find_Orb
; first looks for ephemeris files specified in 'environ.dat',  as described
; at     http://projectpluto.com/find_orb.htm#de_eph
;
;    But if you haven't specified a JPL ephemeris file,  Find_Orb looks
; through this list.  That lets you simply drop a JPL ephem file into the
; Find_Orb folder,  and have Find_Orb figure it out on its own.
;
;   The files listed are assorted JPL binary ephemerides found on-line or
; the Willmann-Bell CD,  or distributed with Guide 8.0 or 9.0.  Byte order
; is not a problem;  the software will flip bytes as needed.
;
;    If Find_Orb doesn't locate a JPL ephemeris file,  it'll still run.  It
; just may be noticeably slower in some situations.
