entry函数, 这个函数主要用来存储索引的，例如下面的：

	function index()
19	    entry({"admin", "system"}, alias("admin", "system", "system"), _("System"), 30).index = true
20	    entry({"admin", "system", "system"}, cbi("admin_system/system"), _("System"), 1)
21	    entry({"admin", "system", "clock_status"}, call("action_clock_status"))
22
23	    entry({"admin", "system", "admin"}, cbi("admin_system/admin"), _("Administration"), 2)
24
25	    if nixio.fs.access("/bin/opkg") then
26	        entry({"admin", "system", "packages"}, call("action_packages"), _("Software"), 10)
27	        entry({"admin", "system", "packages", "ipkg"}, form("admin_system/ipkg"))
28	    end
29
30	    entry({"admin", "system", "startup"}, form("admin_system/startup"), _("Startup"), 45)
31	    entry({"admin", "system", "crontab"}, form("admin_system/crontab"), _("Scheduled Tasks"), 46)
32
33	    if nixio.fs.access("/etc/config/fstab") then
34	        entry({"admin", "system", "fstab"}, cbi("admin_system/fstab"), _("Mount Points"), 50)
35	        entry({"admin", "system", "fstab", "mount"}, cbi("admin_system/fstab/mount"), nil).leaf = true
36	        entry({"admin", "system", "fstab", "swap"},  cbi("admin_system/fstab/swap"),  nil).leaf = true
37	    end
38
39	    if nixio.fs.access("/sys/class/leds") then
40	        entry({"admin", "system", "leds"}, cbi("admin_system/leds"), _("<abbr title=\"Light Emitting Diode\">LED</abbr> Configuration"), 60)
41	    end
42
43	    entry({"admin", "system", "flashops"}, call("action_flashops"), _("Backup / Flash Firmware"), 70)
44	    entry({"admin", "system", "flashops", "backupfiles"}, form("admin_system/backupfiles"))
