"""Use inotify to watch a directory and execute a command on file change.

Watch for any file change below current directory (using inotify via pyinotify)
and execute the given command on file change.

Just using inotify-tools `while inotifywait -r -e close_write .; do something; done`
has many issues which are fixed by this tools:
 * If your editor creates a backup before writing the file, it'll trigger multiple times.
 * If your directory structure is deep, it'll have to reinitialize inotify after each change.
