 * Project:  Shapelib
 * Purpose:  
 *   Altered "shpdump" and "dbfdump" to allow two files to be appended.
 *   Other Functions:
 *     Selecting from the DBF before the write occurs.
 *     Change the UNITS between Feet and Meters and Shift X,Y.
 *     Clip and Erase boundary.  The program only passes thru the
 *     data once.
 *
 *   Bill Miller   North Carolina - Department of Transporation 
 *   Feb. 1997 -- bmiller@dot.state.nc.us
 *         There was not a lot of time to debug hidden problems;
 *         And the code is not very well organized or documented.
 *         The clip/erase function was not well tested.
 *   Oct. 2000 -- bmiller@dot.state.nc.us
 *         Fixed the problem when select is using numbers
 *         larger than short integer.  It now reads long integer.
 *   NOTE: DBF files created using windows NT will read as a string with
 *         a length of 381 characters.  This is a bug in "dbfopen".
