* set the override_redirect flag. Clients are organized in a global
* doubly-linked client list, the focus history is remembered through a global
* stack list. Each client contains an array of Bools of the same size as the
- * global tags array to indicate the tags of a client. For each client dwm
- * creates a small title window, which is resized whenever the (_NET_)WM_NAME
- * properties are updated or the client is moved/resized.
+ * global tags array to indicate the tags of a client.
*
- * Keys and tagging rules are organized as arrays and defined in the config.h
- * file. These arrays are kept static in event.o and tag.o respectively,
- * because no other part of dwm needs access to them. The current layout is
- * represented by the lt pointer.
