1 ;;; This is the master value for LISP-IMPLEMENTATION-VERSION. It's
2 ;;; separated into its own file here so that it's easy for
3 ;;; text-munging make-ish or cvs-ish scripts to find and tweak it. For
4 ;;; the convenience of such scripts, only a simple subset of Lisp
5 ;;; reader syntax should be used here: semicolon-delimited comments,
6 ;;; possible blank lines or other whitespace, and a single
7 ;;; double-quoted string value alone on its own line.
9 ;;; ANSI says LISP-IMPLEMENTATION-VERSION can be NIL "if no
10 ;;; appropriate and relevant result can be produced", but as long as
11 ;;; we control the build, we can always assign an appropriate and
12 ;;; relevant result, so this must be a string, not NIL.
14 ;;; Conventionally a string like "0.6.6", with three numeric fields,
15 ;;; is used for released versions, and a string like "0.6.5.xyzzy",
16 ;;; with something arbitrary in the fourth field, is used for CVS
17 ;;; checkins which aren't released. (And occasionally for internal
18 ;;; versions, especially for internal versions off the main CVS
19 ;;; branch, it gets hairier, e.g. "0.pre7.14.flaky4.13".)
