;; FILES TO BE GENERATED
;;
;;   The entry function `unidata-gen-files' generates these files in
;;   in directory specified by its dest-dir argument.
;;
;;   charprop.el
;;      It contains a series of forms of this format:
;;        (define-char-code-property PROP FILE)
;;      where PROP is a symbol representing a character property
;;      (name, general-category, etc), and FILE is a name of one of
;;      the following files.
;;
;;   uni-name.el, uni-category.el, uni-combining.el, uni-bidi.el,
;;   uni-decomposition.el, uni-decimal.el, uni-digit.el, uni-numeric.el,
;;   uni-mirrored.el, uni-old-name.el, uni-comment.el, uni-uppercase.el,
;;   uni-lowercase.el, uni-titlecase.el
;;      They contain one or more forms of this format:
;;        (define-char-code-property PROP CHAR-TABLE)
;;      where PROP is the same as above, and CHAR-TABLE is a
;;      char-table containing property values in a compressed format.
;;
;;   When they are installed in .../lisp/international/, the file
;;   "charprop.el" is preloaded in loadup.el.  The other files are
;;   automatically loaded when the Lisp functions
;;   `get-char-code-property' and `put-char-code-property', and C
;;   function uniprop_table are called.
;;
;; FORMAT OF A CHAR TABLE
;;
;;   We want to make a file size containing a char-table small.  We
;;   also want to load the file and get a property value fast.  We
;;   also want to reduce the used memory after loading it.  So,
;;   instead of naively storing a property value for each character in
;;   a char-table (and write it out into a file), we store compressed
;;   data in a char-table as below.
;;
;;   If succeeding 128*N characters have the same property value, we
;;   store that value (or the encoded one) for them.  Otherwise,
;;   compress values (or the encoded ones) for succeeding 128
;;   characters into a single string and store it for those
;;   characters.  The way of compression depends on a property.  See
;;   the section "SIMPLE TABLE", "RUN-LENGTH TABLE", and "WORD-LIST
;;   TABLE".

;;   The char table has five extra slots:
;;      1st: property symbol
;;      2nd: function to call to get a property value,
;;           or an index number of C function to decode the value,
;;           or nil if the value can be directly got from the table.
;;      3nd: function to call to put a property value,
;;           or an index number of C function to encode the value,
;;           or nil if the value can be directly stored in the table.
;;      4th: function to call to get a description of a property value, or nil
;;      5th: data referred by the above functions

;; List of elements of this form:
;;   (CHAR-or-RANGE PROP1 PROP2 ... PROPn)
;; CHAR-or-RANGE: a character code or a cons of character codes
;; PROPn: string representing the nth property value
