9 NOTES
10
11 Remember to append a ISTILE line like that one in your config.h:
12
13 #define ISTILE isarrange(tile) || isarrange(ntile) || isarrange(dntile) || isarrange(tilecols)
14
15
16 INSTALLATION
17
18 Copy this file into the dwm root directory (the one) and follow the instructions
19 related into the configuration section.
20
21
22 CONFIGURATION
23
24 You should modify your config.h to include "nmaster.c" from it after
25 setting the NMASTER, NCOLS and NROWS macro definitions.

28 *** NMASTER ***
29
30 #define NMASTER 1
31 #include "nmaster.c"
32
33 Layout layouts[] = {
34 { "-|=", ntile }, /* first entry is default */

36 { MODKEY|ShiftMask, XK_j, setnmaster, "+1"}, \

41 *** TILECOLS ***
42
43 #define NCOLS 2

56 *** CLIENTS PER TAG ***
57
58 Valid values are:
59 -1 - show all clients
60 0 - show no clients
61 >0 - show N clients
62
63 Example configuration:
64 { MODKEY|ShiftMask, XK_q, clientspertag, "0" }, \
65 { MODKEY, XK_q, clientspertag, "^1" }, \
66 { MODKEY, XK_w, clientspertag, "^2" }, \
