+clientopacity
+=========
+
+Description
+-----------
+This patch adds a default transparency parameter to config.h, which specifies the
+transparency, all windows are started with. It also adds opacity to the ruleset, enabling to override the opacity on a per client basis.
+
+Additionally it adds some shortcuts:
+
+* MOD + Shift + Numpad_Add -> increase opacity of current focused window
+* MOD + Shift + Numpad_Subtract -> decrease opacity of current focused window
+
+It is based on the transparency patch of Christop Lohmann.
