[Xastir] Shapefile creation help?

On Fri, Apr 22, 2005 at 01:08:27AM -0700, we recorded a bogon-computron collision of the <change-xastir at nightwind.net> flavor, containing:

You put the coordinates in the wrong order --- you used "latitude longitude"
and xastir is expecting "longitude latitude"

That isn't explicitly stated in README.MAPS, but the lines:
       shpcreate posts point
       dbfcreate posts -n ID 8 0 -s CFCC 3 -s NAME 30
       shpadd posts -74.0570 40.6025
       dbfadd posts 1 'X\m ' Start

are supposed to be creating a point in North America, so -74.0570 is the 
longitude.

HTH,
