+.TH ROUTE 1
+.SH NAME
+route \- map orientations and great circle paths
+.SH SYNOPSIS
+.B route
+[ 
+.B -t
+]
+.SH DESCRIPTION
+.I Route
+without an option
+reads from the standard input a sequence of points, expressed 
+as latitude-longitude pairs.
+For each pair of points, say A and B,
+.I route
+prints on the standard output
+.IP \-
+A
+.IR map (7)
+orientation, expressed as a
+.B -o
+option, that transforms the great circle from A to B into the equator.
+The transformed locations of A and B are located on the equator
+at equal distances west and east of the Prime Meridian.
+.IP \-
+The transformed coordinates of the two points.
+.IP \-
+The same information for a map orientation in which point A
+appears to the east and B to the west of the Prime Meridian.
+.PP
+Under option
+.B -t
+.I route
+produces coordinates along the great circle from A to B
+in the form of a track for use with 
+.I map
+option
+.BR -t .
+.PP
+Coordinates are expressed in degrees, with latitude
+positive north of the equator and longitude positive
+west of Greenwich.
+.SH EXAMPLES

+From this we derive the following command to draw a strip map 
+20 degrees wide along the great circle from New York to London.
+The
+.B -w
+option windows the map in the new coordinate system, where
+the equator runs along the great circle and the two cities
+sit at 25W and 25E on that `equator'.
+The
+.B -l
+option avoids surveying the whole rest of the world for
+plottable points.
