     8.6 + *
     8.7 + * dynamic window manager is designed like any other X client as well. It is
     8.8 + * driven through handling X events. In contrast to other X clients, a window
     8.9 + * manager selects for SubstructureRedirectMask on the root window, to receive
    8.10 + * events about window (dis-)appearance.  Only one X connection at a time is
    8.11 + * allowed to select for this event mask.
    8.12 + *
    8.13 + * Calls to fetch an X event from the event queue are blocking.  Due reading
    8.14 + * status text from standard input, a select()-driven main loop has been
    8.15 + * implemented which selects for reads on the X connection and STDIN_FILENO to
    8.16 + * handle all data smoothly. The event handlers of dwm are organized in an
    8.17 + * array which is accessed whenever a new event has been fetched. This allows
    8.18 + * event dispatching in O(1) time.
    8.19 + *
    8.20 + * Each child of the root window is called a client, except windows which have
    8.21 + * set the override_redirect flag.  Clients are organized in a global
    8.22 + * doubly-linked client list, the focus history is remembered through a global
    8.23 + * stack list. Each client contains an array of Bools of the same size as the
    8.24 + * global tags array to indicate the tags of a client.  For each client dwm
    8.25 + * creates a small title window, which is resized whenever the (_NET_)WM_NAME
    8.26 + * properties are updated or the client is moved/resized.
    8.27 + *
    8.28 + * Keys and tagging rules are organized as arrays and defined in the config.h
    8.29 + * file. These arrays are kept static in event.o and tag.o respectively,
    8.30 + * because no other part of dwm needs access to them.  The current mode is
    8.31 + * represented by the arrange() function pointer, which wether points to
    8.32 + * dofloat() or dotile().
    8.33 + *
    8.34 + * To understand everything else, start reading main.c:main().

     9.6 - *
     9.7 - * dynamic window manager is designed like any other X client as well. It is
     9.8 - * driven through handling X events. In contrast to other X clients, a window
     9.9 - * manager selects for SubstructureRedirectMask on the root window, to receive
    9.10 - * events about window (dis-)appearance.  Only one X connection at a time is
    9.11 - * allowed to select for this event mask.
    9.12 - *
    9.13 - * Calls to fetch an X event from the event queue are blocking.  Due reading
    9.14 - * status text from standard input, a select()-driven main loop has been
    9.15 - * implemented which selects for reads on the X connection and STDIN_FILENO to
    9.16 - * handle all data smoothly. The event handlers of dwm are organized in an
    9.17 - * array which is accessed whenever a new event has been fetched. This allows
    9.18 - * event dispatching in O(1) time.
    9.19 - *
    9.20 - * Each child of the root window is called a client, except windows which have
    9.21 - * set the override_redirect flag.  Clients are organized in a global
    9.22 - * doubly-linked client list, the focus history is remembered through a global
    9.23 - * stack list. Each client contains an array of Bools of the same size as the
    9.24 - * global tags array to indicate the tags of a client.  For each client dwm
    9.25 - * creates a small title window, which is resized whenever the (_NET_)WM_NAME
    9.26 - * properties are updated or the client is moved/resized.
    9.27 - *
    9.28 - * Keys and tagging rules are organized as arrays and defined in the config.h
    9.29 - * file. These arrays are kept static in event.o and tag.o respectively,
    9.30 - * because no other part of dwm needs access to them.  The current mode is
    9.31 - * represented by the arrange() function pointer, which wether points to
    9.32 - * dofloat() or dotile(). 
    9.33 - *
    9.34 - * To understand everything else, start reading main.c:main().
