+Xresources
+==========
+
+Description
+-----------
+This patch allows to handle settings from Xresources. It differs from xrdb patch in that it can handle any kind of setting as opposed to only color settings.
+
+Settings in config.h
+--------------------
+In `resources` struct is written the name, the type, and the address of the setting.
+
+ Name Type Address
+ --------------------------------------------------------
+ "nmaster" INTEGER &nmaster
+ "mfact" FLOAT &mfact
+ "color1" STRING &color1
+
+In Xresources file setting names shoud be prefixed with "dwm."
+
+ dwm.nmaster:
+ dwm.mfact:
+ dwm.color1:
+
+This patch is a port of the st patch of the same name, it also borrows some code from dwm's xrdb patch, so a thank is in order for the authors of those patches.
