 ;;	vm	- a mail reader
 ;;	[]	Always install
 ;;	[]	Needs updating
 ;;	[]	Required by other [packages]
 ;;
 ;;	Where `[]' indicates a toggle box
 ;;
 ;;	- Clicking on "Always install" puts this into
 ;;	  `package-get-here' list.  "Needs updating" indicates a new
 ;;	  version is available.  Anything already in
 ;;	  `package-get-here' has this enabled.
 ;;	- "Required by other" means some other packages are going to force
 ;;	  this to be installed.  Clicking on  [packages] gives a list
 ;;	  of packages that require this.
 ;;
 ;;	The `package-get-base' should be installed in a file in
 ;;	`data-directory'.  The `package-get-here' should be installed in
 ;;	site-lisp.  Both are then read at run time.
