; folks from using this.
(defmacro definline (name formals &rest args)
;; Alias for @(see defun-inline)
;; Examples:
;; @({
;; (include-book \"misc/definline\")
;; (definline car-alias (x)
;; (car x))
;; })
;; @('definline') is a wrapper for @(see defun-inline).
;; We probably shouldn't have this wrapper. But until ACL2 5.0 there was no
;; @('defun-inline'), and @('definline') was implemented using a @(see trust-tag).
;; When @('defun-inline') was introduced, we already had many books with
;; @('definline') and liked the shorter name, so we dropped the trust tag and
;; turned it into a wrapper for @('defun-inline').

(defmacro definlined (name formals &rest args)
;; Alias for @(see defund-inline)
;; This is a @(see defund)-like version of @(see definline).
