+Synopsis
+--------
+'pacman-conf' [options] [<directive> ...]
+
+'pacman-conf' (--repo-list|--help|--version)
+
+
+Description
+-----------
+'pacman-conf' is a utility for parsing the 'pacman' configuration file
+and returning script-friendly output. It is designed to properly handle
+non-trivial configuration features such as variable interpolation and
+the use of the Include directive, and guarantees that it will return the
+same configuration values which 'pacman' itself would use.
+
+'pacman-conf' will output the fully-resolved contents of the
+configuration file by default, or, if provided with the name of a
+configuration directive, output the contents of the given directive alone.
+
+
+Options
+-------
+*-c, \--config* <path>::
+	Specify an alternate configuration file.
+
+*-R, \--rootdir* <path>::
+	Specify an alternate installation root (default is `/`).

+*-v, \--verbose*::

+*-l, \--repo-list*::

+
+*-h, \--help*::

+*-V, \--version*::
