;;; Commentary:
;; This package implements a backend for org-sync to synchnonize
;; issues from a bitbucket repo with an org-mode buffer. Read
;; Org-sync documentation for more information about it.
;; This backend only supports basic synchronization for now.
;; Components, versions and milestones are ignored.
