The files included in this directory, Makefile and tar file Radar_lib.tar, are
used to build the shared object module which cdaweb uses for display of radar
plots. There are several platform dependencies built into the Makefile.

=> tar -xvf Radar_lib.tar        - extracts the files
=> make                          - builds LIB_PGM.so

Include the path to this library in the LD_LIBRARY_PATH environment variable 
when executing idl.
