+command shells.  It works by creating an object that caches the original
+working directory.  When the object is destroyed, the destructor calls
+@code{chdir} to revert to the original working directory.  By storing the
+object in a lexical variable with a limited scope, this happens automatically
+at the end of the scope.")
