+operating system interactions that are useful when exploring a filesystem on a
+remote host.  Pox provides Python equivalents of several shell commands such
+as @command{which} and @command{find}.  These commands allow automated
+discovery of what has been installed on an operating system, and where the
+essential tools are located.")
