NAME
       x_setup - Determine Pairs of Legs that need Cross-Over Checking


SYNOPSIS
       x_setup [ -Llegfile ] [ -Rwest/east/south/north ]


DESCRIPTION
       x_setup  scans  the gmtindex.b file that contains information on which legs occupy each 1 by 1 degree bin
       and reports all the pairs of legs that may overlap. Each pair is only reported once, even if the two legs
       involved are found in other bins also.

       -L     Only report pairs where at least one of the legs are present in the legfile.

       -R     The region of interest.  [Default is world]


BEWARE
       The  -L  option is useful when one wants to check out a handful of new cruises. Obviously we only need to
       compute COEs for the pairs that involve one or two of the new cruises, since all the  other  combinations
       have already been done.
