;;; Commentary:
;; This file adds support for `enumitem.sty' (v3.9) from 2019/06/20.
;; `enumitem.sty' is part of TeXLive.
;; Tassilo Horn's `minted.el' was a major source of inspiration for
;; this style, many thanks to him (also for patiently answering my
;; many other questions, incl. the stupid ones.)
;; If things do not work or when in doubt, press `C-c C-n'. Comments
;; for improvement are welcome.
;;; Code:
(require 'tex)
(require 'latex)
(eval-when-compile
(require 'cl-lib))
;; Silence the compiler:
