/*!
  Constructs a DocLnkSet that contains DocLnk objects representing all
  the files in the \a directory (and any subdirectories, recursively).

  If \a mimefilter is not null,
  only documents with a MIME type matching \a mimefilter are selected.
  The value may contain multiple wild-card patterns separated by ";",
  such as \c{*o/mpeg;audio/x-wav}.
