    Autostart patch I made
    
    It processes an array of arrays of strings and executes it using execvp().
    It also kills all started processes at quit.

+Cool autostart
+==============
+
+Deskription
+-----------
+Allow dwm to execute commands from `autostart` array in youre config.h file.
+And when you exit dwm all processes from `autostart` array would be killed.
+
+Example
+-------
+
+ static char* const autostart[][4] = {
+ { "mpd-notification", NULL },
+ { "hsetroot", "-center", "/usr/home/bit6tream/pic/wallapper.png", NULL },
+ { "xrdb", "/usr/home/bit6tream/.config/X/Xresources", NULL },
+ { "sh", "-c", "while :; do dwmstatus.sh -; sleep 60; done", NULL },
+ { "dunst", NULL },
+ { "picom", NULL }
+ };
+
+Attention
+---------
+Commands from array are executed using execvp().
+So if you need to execute shell command you need to prefix it with
+`"sh", "-c"` (change `sh` to any shell you like).
