;;; Commentary:
;;
;; In an ideal world, faces should work sensibly:
;;
;; a) with default colours
;; b) with -rv
;; c) on console
;; d) on different Emacsen/architectures (win32, mac, etc)
;;
;; But it's difficult to keep track of all that!
;; Please report any bad/failing colour
;; combinations (with suggested improvements) at
;; https://github.com/ProofGeneral/PG/issues
;;
;; Some of these faces aren't used by default in Proof General,
;; but you can use them in font lock patterns for specific
;; script languages.
;;; Code:
(defgroup proof-faces nil
"Faces used by Proof General."
:group 'proof-general
:prefix "proof-")
;; TODO: get rid of this list. Does 'default work widely enough
;; by now?
