;; CCL:SOURCE-NOTE-END-POS and CCL:SOURCE-NOTE-TEXT. The start and end
;; positions are file positions (not character positions). The text will
;; be NIL unless text recording was on at read-time. If the original
;; file is still available, you can force missing source text to be read
;; from the file at runtime via CCL:ENSURE-SOURCE-NOTE-TEXT.
;;
;; Source-note's are associated with definitions (via record-source-file)
;; and also stored in function objects (including anonymous and nested
;; functions). The former can be retrieved via
;; CCL:FIND-DEFINITION-SOURCES, the latter via CCL:FUNCTION-SOURCE-NOTE.
;;
;; The recording behavior is controlled by the new variable
;; CCL:*SAVE-SOURCE-LOCATIONS*:
;;
;; If NIL, don't store source-notes in function objects, and store only
;; the filename for definitions (the latter only if
;; *record-source-file* is true).
;;
;; If T, store source-notes, including a copy of the original source
;; text, for function objects and definitions (the latter only if
;; *record-source-file* is true).
;;
;; If :NO-TEXT, store source-notes, but without saved text, for
;; function objects and defintions (the latter only if
;; *record-source-file* is true). This is the default.
;;
;; PC to source mapping is controlled by the new variable
;; CCL:*RECORD-PC-MAPPING*. If true (the default), functions store a
;; compressed table mapping pc offsets to corresponding source locations.
;; This can be retrieved by (CCL:FIND-SOURCE-NOTE-AT-PC function pc)
;; which returns a source-note for the source at offset pc in the
;; function.
