Usage: Watch [-v] [-t] [-p <path>] [-x <regexp>] <command>

Watches for changes in a directory tree, and runs a command when something changed. By default, the output goes to an acme win.

-t sends the output to the terminal instead of acme

-v enables verbose debugging output

-p specifies the path to watch (if it is a directory then it watches recursively)

-x specifies a regexp used to exclude files and directories from the watcher.
