+Subject: [PATCH] Unmanaged patch for dwm
+
+This patch adds a new rule option allowing the user to specify windows that
+are not supposed to be managed by the window manager.
+
+This may include external bars, conky, widgets or desktop icons.
+
+If a window is unmanaged then its size and position is controlled by the
+window application itself, or you can control these using external tools.
+
+As such you will not be able to resize or move a window within dwm like
+normal managed windows are.
+
+The patch adds a new rule option "unmanaged" that is intentionally placed
+at the end of the rules options. This is because as long as the field is
+at the very end you do not actually need to specify a value (it will
+default to 0) which means that existing rules can be left as-is.
+
+	/* class      instance    title       tags mask     isfloating   monitor  unmanaged */
+	{ "Gimp",     NULL,       NULL,       0,            1,           -1,      0 },
+	{ "Firefox",  NULL,       NULL,       1 << 8,       0,           -1,      0 },
+
+Whether unmanaged windows should stay on top of other windows or not depends
+very much on the program. It may be desirable to place a bar on top of other
+windows whereas an application that provides desktop icons is naturally best
+placed below all other windows.
+
+As such the value of the unmanged rule plays a part:
+   * 0 - the window is managed by the window manager
+   * 1 - the window will be placed above all other windows
+   * 2 - the window will be placed below all other windows
+   * 3 - the window is left as-is (neither lowered nor raised)
