;;; Commentary:
|
|
|
|
;; Provides fairly minimal font-lock, imenu and indentation support
|
|
;; for editing configure.in files. Only Autoconf syntax is processed.
|
|
;; There is no attempt to deal with shell text -- probably that will
|
|
;; always lose.
|
|
|
|
;; This is specialized for configure.in files. It doesn't inherit the
|
|
;; general M4 stuff from M4 mode.
|
|
|
|
;; There is also an autoconf-mode.el in existence. That appears to be
|
|
;; for editing the Autoconf M4 source, rather than configure.in files.
