Checksum32 installation

1. Unpack the tarball containing the CRC32 distribution:
   

       gunzip -c chksum32.tar.gz | tar xvf -   

2. That will create the chksum32 directory: move to the chksum32/src directory and invoke make:

       cd chksum/src
       make clean all

3. That will create an executable called crc32. You can invoke that executable to compute the checksum for a file by giving the file's pathname on the commmand line:
   

       $ ./crc32 crc32.c
   
       Calculating CRC for file: crc32.c
       Read 7883 bytes, CRC32 Checksum is 482575795
