29 ;; The major mode for editing Scheme-type Lisp code, very similar to
30 ;; the Lisp mode documented in the Emacs manual. `dsssl-mode' is a
31 ;; variant of scheme-mode for editing DSSSL specifications for SGML
32 ;; documents. [As of Apr 1997, some pointers for DSSSL may be found,
33 ;; for instance, at <URL:http://www.sil.org/sgml/related.html#dsssl>.]
34 ;; All these Lisp-ish modes vary basically in details of the language
35 ;; syntax they highlight/indent/index, but dsssl-mode uses "^;;;" as
36 ;; the page-delimiter since ^L isn't normally a legal SGML character.
38 ;; For interacting with a Scheme interpreter See also `run-scheme' in
39 ;; the `cmuscheme' package and also the implementation-specific
42 ;; Here's a recipe to generate a TAGS file for DSSSL, by the way:
43 ;; etags --lang=scheme --regex='/[ \t]*(\(mode\|element\)[ \t
45 ;; ]+\)/\2/' --regex='/[ \t]*(element[ \t
48 ;; ]*)/\1/' --regex='/(declare[^ \t
