1) TO BUILD

   Edit the Makefile to set the compilers that will be used. Depending on which
   Fortran compiler and compiler flags are used, it may be necessary to set the
   value of CFLAGS to -D_UNDERSCORE, -D_DOUBLEUNDERSCORE, or nothing. The 
   proper setting for the variables in the Makefile can usually be determined
   by looking in the configure.wps file used to compile the WPS.

   Also, before building the code, it will be necessary to set the dimensions of
   the data set in the rd_wr_binary.f90 file. By default, these are nx=1200 and
   ny=1200.

2) TO RUN

   Type "./rd_wr_binary.exe <filename>" on the command line, where <filename> is 
   the name of a binary file to be processed by the program. After successfully 
   running, a file <filename>.new should be created.
