       This program allows a user to interactively: convert coor-
       dinates 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 - northing - ground coordinates



       For example:

	     500000.00	   4496918.64
	    -424489.11	   1908736.13




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