meillo@754 4 *
meillo@754 5 * dynamic window manager is designed like any other X client as well. It is
meillo@754 6 * driven through handling X events. In contrast to other X clients, a window
meillo@754 7 * manager selects for SubstructureRedirectMask on the root window, to receive
meillo@754 8 * events about window (dis-)appearance. Only one X connection at a time is
meillo@754 9 * allowed to select for this event mask.
meillo@754 10 *
meillo@777 11 * The event handlers of dwm are organized in an array which is accessed
meillo@777 12 * whenever a new event has been fetched. This allows event dispatching in O(1)
meillo@777 13 * time.
meillo@754 14 *
meillo@754 15 * Each child of the root window is called a client, except windows which have
meillo@754 16 * set the override_redirect flag. Clients are organized in a global
meillo@754 17 * doubly-linked client list, the focus history is remembered through a global
meillo@766 18 * stack list. [...]
meillo@754 19 *
meillo@754 20 * Keys and tagging rules are organized as arrays and defined in the config.h
meillo@771 21 * file. [...] The current mode is represented by the arrange() function
meillo@771 22 * pointer, which wether points to [domax()] or dotile().
meillo@754 23 *
meillo@754 24 * To understand everything else, start reading main.c:main().
meillo@766 25 *
meillo@766 26 * -- and now about aewl --
meillo@766 27 *
meillo@766 28 * aewl is a stripped down dwm. It stated as a patchset, but finally forked off
meillo@766 29 * completely. The reason for this was the increasing gap between my wish to
meillo@766 30 * stay where dwm was, and dwm direction to go further. Further more did I
meillo@766 31 * always use only a small subset of dwm's features, so condencing dwm had been
meillo@766 32 * my wish for a long time.
meillo@766 33 *
meillo@766 34 * In aewl clients are either tagged or not (only one tag). Visible are either
meillo@766 35 * all tagged clients or all without the tag.
