29 ;; CCL (Code Conversion Language) is a simple programming language to
|
|
|
30 ;; be used for various kind of code conversion. CCL program is
|
|
|
31 ;; compiled to CCL code (vector of integers) and executed by CCL
|
|
|
32 ;; interpreter of Emacs.
|
|
|
33 ;;
|
|
|
34 ;; CCL is used for code conversion at process I/O and file I/O for
|
|
|
35 ;; non-standard coding-system. In addition, it is used for
|
|
|
36 ;; calculating a code point of X's font from a character code.
|
|
|
37 ;; However, since CCL is designed as a powerful programming language,
|
|
|
38 ;; it can be used for more generic calculation. For instance,
|
|
|
39 ;; combination of three or more arithmetic operations can be
|
|
|
40 ;; calculated faster than Emacs Lisp.
|
