;   'extraloc.txt' provides additional observer locations that didn't
; fit logically in the 'world cities' or 'US cities' or similar files.
; Most of these are landing sites of lunar/planetary missions.
;
;   You can add still more such locations in 'user_loc.txt'.  It's well
; to put such locations there,  because when you do an update,  this
; 'extraloc.txt' file will be replaced.  To make sure locations you create
; don't get overwritten,  put them in 'user_loc.txt'.  (The formats of
; the files are identical.)
;
;   Locations are given in the form:  Latitude,  Longitude,  Altitude
; (in meters),  Name as entered in "Enter location name:",  and the
; name as it should be displayed on the title bar.  One line is given
; for each of these five entries.
;
;   For example:  the first entry indicates that if you enter "prpl"
; in the "Enter Location name:" dialog,  Guide will reset the lat/lon
; to N 44.021, W 69 53 18.6,  at an altitude of 100 meters.  The title
; bar will indicate that Guide is now showing the universe as seen
; from Project Pluto's corporate headquarters in Bowdoinham,  Maine.
;
;   You can use decimal degrees,  or degrees and decimal minutes,  or
; degrees,  minutes,  and decimal seconds.
;
;   For locations off the Earth,  the altitude can be followed by a
; comma and a planet number (10=the moon,  1=Mercury,  2=Venus,  etc.)
; Some examples for the Apollo landing sites and some of the Mars
; probes are given.
;
;   The Italian-language version of this file would be 'ixtraloc.txt',
; the French 'fxtraloc.txt',  and so on.
