       This  program  allows a user to interactively: convert coordinates from
       one projection to another



       It allows a user to do all of the above:
	      reading from a file, writing to the screen,  or reading from the
	      keyboard,  writing to a file, or reading from a file, writing to
	      a file,



       Note:  The program does not transform GRASS files, it  is  designed  to
       determine coordinate values on an individual position.


       The  map  projections currently supported are listed in etc/projections
       file


       Each of the above projections (with the exception of State  Plane)  can
       be computed with the spheroids listed in etc/ellipse.table file

       When reading from a file of LATITUDE/LONGITUDE data the
	      file  will  contain  three (2) columns of information: the first
	      column - latitude   - in degrees	minutes  seconds,  the	second
	      column - longitude - in degrees minutes seconds,



       For example:

	    +40 36 31.4563 -87 2 7.8193
	    40n 36 31.4563 87w 2 7.8193




       When reading from a file of PROJECTION COORDINATES data the
	      file  will  contain  three (2) columns of information: the first
	      column - easting - ground coordinates the second column  -  nor-
	      thing - ground coordinates



       For example:

	     500000.00	   4496918.64
	    -424489.11	   1908736.13




       NNoottee:: NO column headings are required, just the numbers.
