It manages windows in tiled, monocle +and floating layouts. Either layout can be applied dynamically, optimising the +environment for the application in use and the task performed. +.P +In tiled layouts windows are managed in a master and stacking area. The master +area on the left contains one window by default, and the stacking area on the +right contains all other windows. The number of master area windows can be +adjusted from zero to an arbitrary number. In monocle layout all windows are +maximised to the screen size. In floating layout windows can be resized and +moved freely. Dialog windows are always managed floating, regardless of the +layout applied. +.P +Windows are grouped by tags. Each window can be tagged with one or multiple +tags. Selecting certain tags displays all windows with these tags. +.P +Each screen contains a small status bar which displays all available tags, the +layout, the title of the focused window, and the text read from the root window +name property, if the screen is focused. A floating window is indicated with an +empty square and a maximised floating window is indicated with a filled square +before the windows title. The selected tags are indicated with a different +color. The tags of the focused window are indicated with a filled square in the +top left corner. The tags which are applied to one or more windows are +indicated with an empty square in the top left corner. +.P +dwm draws a small border around windows to indicate the focus state. +.SH OPTIONS +.TP +.B \-v +prints version information to stderr, then exits. +.SH USAGE +.SS Status bar +.TP +.B X root window name +is read and displayed in the status text area.
