INSTALLATION:

  See also hyrolo.el. These functions are separated from hyrolo.el since
  many users may never want or need them. They can be automatically
  loaded when desired by adding the following to one of your Emacs init
  files:

   (autoload 'hyrolo-fgrep-logical "hyrolo-logic" "Rolo search with
   logical operators." t)

 FEATURES:

  1. One command, hyrolo-fgrep-logical which prompts for a logical
      search expression string and displays any matching entries. A
      sample expression might be:
       (and (or (not time card) (xor "french balloons" spanish))
                teacher pet)

      By default, only sub-entries with matches are shown, not entire
      hierarchies of entries, for more intuitive results.

      Either double quotes or parentheses may be used to group multiple
      words as a single argument.

  2. Logical hyrolo-and, hyrolo-or, hyrolo-not, and hyrolo-xor
      rolo entry string filter functions. They take any number of string
      or boolean arguments and may be nested. NOTE THAT THESE FUNCTIONS
      SHOULD NEVER BE CALLED DIRECTLY UNLESS THE FREE VARIABLES start
      and end ARE BOUND BEFOREHAND.

  3. Logical hyrolo-r-and, hyrolo-r-or, hyrolo-r-not, and
      hyrolo-r-xor' rolo entry regexp filter functions. They take any
      number of string or boolean arguments and may be nested. NOTE THAT
      THESE FUNCTIONS SHOULD NEVER BE CALLED DIRECTLY UNLESS THE FREE
      VARIABLES start and end ARE BOUND BEFOREHAND.

 EXAMPLE PROGRAMMATIC USAGE:

    (hyrolo-logic (hyrolo-and (hyrolo-not "Tool-And-Die") "secretary"))

  would find all non-Tool-And-Die Corporation secretaries in your rolo.

  The logical matching routines are not at all optimal, but then most
  rolo files are not terribly lengthy either, so results are often
  displayed quickly.
