How can I calculate an md5 checksum of a directory?
...md5sums are sorted.
The md5sum of this sorted list is then returned.
I've tested this by copying a test directory:
rsync -a ~/pybin/ ~/pybin2/
I renamed some of the files in ~/pybin2.
The find...md5sum command returns the same output for both directories.
