Maybe the list of two-element lists *is* preferable? There is a subtle
order sometimes implied by summary information, anyway. One possible
- [A, file1.txt]
- [M, file1.txt]
- [Move, file1.txt, file2.txt]
- [M, file2.txt]

True to a point, but I've still seen almost my fair share of old shell
scripts that have to be rejiggered due to subtle changes in some other
Also, Python is as fine and qualified as a shell scripting language as
perl is (Python even has -e), if not better (for being more readable :P).
