I wrote this program to make md5 checksums for directory trees.
It generates a file in each directory, whose name is specified by the CKNAME
variable. When rerun, if there are any differenes, the old file is renamed to
OLD_CKNAME, and a new file is created. diff is run on the two files, and the
differences are written to standard output.

The program should work anywhere there is a python 2.6 or newer interpreter.

To use the program,
md5sum.py . > a_log_file.txt
