* dynamic window manager is designed like any other X client as well. It is
* driven through handling X events. In contrast to other X clients, a window
*
* 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 mode is
- * represented by the arrange() function pointer, which wether points to
- * dofloat() or dotile().
+ * because no other part of dwm needs access to them. The current layout is
+ * represented by the lt pointer.
*
* To understand everything else, start reading main.c:main().
