+		:UseVimball [path]			*:UseVimball*
+
+	This command is contained within the vimball itself; it invokes the
+	vimball#Vimball() routine which is responsible for unpacking the
+	vimball.  One may choose to execute it by hand instead of sourcing
+	the vimball; one may also choose to specify a path for the

+	existing directory on the |'runtimepath'|.
+
+		:RmVimball vimballfile [path]		*:RmVimball*
+
+	This command removes all files generated by the specified vimball
+	(but not any directories it may have made).  One may choose a path
+	for de-installation, too (see |'runtimepath'|); otherwise, the
+	default is the first existing directory on the |'runtimepath'|.
+	To implement this, a file (.VimballRecord) is made in that directory
+	containing a record of what files need to be removed for all vimballs
+	used thus far.
