Eelco Dolstra e1a6fb7870 * `dependencyClosure' now allows a search path, e.g.,
dependencyClosure { ... searchPath = [ ../foo ../bar ]; ... }

* Primop `dirOf' to return the directory part of a path (e.g., dirOf
  /a/b/c == /a/b).

* Primop `relativise' (according to Webster that's a real word!) that
  given paths A and B returns a string representing path B relative
  path to A; e.g., relativise /a/b/c a/b/x/y => "../x/y".
