;;; Commentary:
;; This library implements support for listing repositories. This
;; includes getting a Lisp list of known repositories as well as a
;; mode for listing repositories in a buffer.
;;; Code:
(eval-when-compile
(require 'subr-x))
(require 'magit-core)
(declare-function magit-status-setup-buffer "magit-status" (directory))
(defvar x-stretch-cursor)
;;; Options

"List of directories that are or contain Git repositories.
Each element has the form (DIRECTORY . DEPTH). DIRECTORY has
to be a directory or a directory file-name, a string. DEPTH,
an integer, specifies the maximum depth to look for Git
repositories. If it is 0, then only add DIRECTORY itself.
This option controls which repositories are being listed by
`magit-list-repositories'. It also affects `magit-status'
\(which see) in potentially surprising ways."

tree. It has to return a string to be inserted or nil. PROPS is
an alist that supports the keys `:right-align' and `:pad-right'.
