Comment(by dsf):

 I have satisfied myself that removeDirectoryRecursive will not follow
 symlinks.  Although doesDirectoryExist will return true for a symlink to
 an existing directory, before that can happen the call to removeFile would
 remove the symlink.  That caution in the documentation can be removed.
