Version: 1.30.0 [2014-04-06]
o Vectorized detachPackage(), getAbsolutePath(), getRelativePath(),
  isAbsolutePath(), isDirectory(), isFile(), isOpen(),
  isPackageInstalled() and touchFile(). Added package system tests
  for several of them.  For backward compatibility, getAbsolutePath(), 
  getRelativePath(), isAbsolutePath(), isFile() and isDirectory() 
  treats an empty vector of path/pathnames equal to ".".  However, 
  in a future version, empty results will returned by these too.
