;; The major mode for editing Scheme-type Lisp code, very similar to
|
|
|
|
|
;; the Lisp mode documented in the Emacs manual. `dsssl-mode' is a
|
|
|
|
|
;; variant of scheme-mode for editing DSSSL specifications for SGML
|
|
|
|
|
;; documents. [As of Apr 1997, some pointers for DSSSL may be found,
|
|
|
|
|
;; for instance, at <URL:http://www.sil.org/sgml/related.html#dsssl>.]
|
|
|
|
|
;; All these Lisp-ish modes vary basically in details of the language
|
|
|
|
|
;; syntax they highlight/indent/index, but dsssl-mode uses "^;;;" as
|
|
|
|
|
;; the page-delimiter since ^L isn't normally a legal SGML character.
|
|
|
|
|
;;
|
|
|
|
|
;; For interacting with a Scheme interpreter See also `run-scheme' in
|
|
|
|
|
;; the `cmuscheme' package and also the implementation-specific
|
|
|
|
|
;; `xscheme' package.
