Copy-on-write directory tree utility
Tries to make copy-on-write semantics upon hard-link copied directory trees generated with 'cp -la' . 'cow-shell' command invokes a shell session. Within that session, under the directory cow-shell was invoked, cowdancer will create a new file when existing i-nodes are opened for write. Useful for quick scratch workspace and experimentation. . For a useful Debian tool, try cowbuilder.
