+dyn-battery
+===========
+
+Description
+-----------
+This patch implements a function that displays the status and capacity of
+all present batteries (only supported for Linux).
+
+The order of the format identifiers is hard-coded: battery number (%u),
+state (%s), capacity (%s). Example:
+"[BAT%u: %s%s]" -> [BAT0: +58]
+
