; 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.

; IMCCE (formerly Bureau des Longitudes) provides ephems in JPL-like format that
; will work with this and some other software. (Not all. For some reason,
; they start blocks at noon instead of midnight. Some programs are confused
; by this.)
