;;; Commentary:
;; This library implements the XEmbed protocol.
;; Usage tips:
;; + Do not forget to call `xcb:xembed:init' for _every_ connection using this
;; library.
;; + Use `xcb:xembed:SendEvent' instead of `xcb:SendEvent' to send XEmbed
;; messages defined in this library.
;; References:
;; + Xembed protocol (https://specifications.freedesktop.org/
