+markup
+------
+
+Made markup easier!
+
+First, require it like this:
+
+    local markup = lain.util.markup
+
+then you can call its functions:
+
+     +-- markup
+     |
+     |`-- bold()        Set bold.
+     |`-- italic()      Set italicized text.
+     |`-- strike()      Set strikethrough text.
+     |`-- underline()   Set underlined text.
+     |`-- monospace()   Set monospaced text.
+     |`-- big()         Set bigger text.
+     |`-- small()       Set smaller text.
+     |`-- font()        Set the font of the text.
+     |
+     |`--+ bg
+     |   |
+     |   |`-- color()   Set background color.
+     |   |`-- focus()   Set focus  background color.
+     |   |`-- normal()  Set normal background color.
+     |    `-- urgent()  Set urgent background color.
+     |
+     |`--+ fg
+     |   |
+     |   |`-- color()   Set foreground color.
+     |   |`-- focus()   Set focus  foreground color.
+     |   |`-- normal()  Set normal foreground color.
+     |    `-- urgent()  Set urgent foreground color.
+     |
+     |`-- focus()       Set both foreground and background focus  colors.
+     |`-- normal()      Set both foreground and background normal colors.
+      `-- urgent()      Set both foreground and background urgent colors.
+
+they all take one argument, which is the text to markup, except `fg.color` and `bg.color`:
+
+    markup.fg.color(text, color)
+    markup.bg.color(text, color)
+
+dynamic tagging
+---------------
+
+That is:
+
+- create a new tag;
+- rename current tag;
+- delete current tag.
+
+If you delete a tag, any rule set on it shall be broken, so be careful.
+
+Use it with key bindings like these:
+
+    awful.key({ modkey, "Shift" }, "n", function () lain.util.create_tag(mypromptbox) end),
+    awful.key({ modkey, "Shift" }, "r", function () lain.util.rename_tag(mypromptbox) end),
+    awful.key({ modkey, "Shift" }, "d", function () lain.util.delete_tag() end),
+
+useless\_gaps\_resize
+---------------------
+
+Changes `beautiful.useless_gaps_width` on the fly.
+
+The function takes an integer argument, being the amount of pixel to add/remove to gaps.
+
+You could use it with these keybindings:
+
+    -- On the fly useless gaps change
+    awful.key({ altkey, "Control" }, "+", function () lain.util.useless_gaps_resize(1) end),
+    awful.key({ altkey, "Control" }, "-", function () lain.util.useless_gaps_resize(-1) end),
+
+where `altkey=Mod1`, or you could use it like this:
+
+    mywidget:buttons(awful.util.table.join (
+          awful.button({}, 4, function() lain.util.useless_gaps_resize(-1) end),
+          awful.button({}, 5, function() lain.util.useless_gaps_resize(1) end)
+          end)
+    ))
+
+so when hovering the mouse over `mywidget`, you can adjust useless gaps size by scrolling with the mouse wheel.
+
+tag\_view\_nonempty
+-------------------
+
+This function lets you jump to the next/previous non-empty tag.
+It takes two arguments:
+
+* `direction`: `1` for next non-empty tag, `-1` for previous.
+* `sc`: Screen which the taglist is in. Default is `mouse.screen` or `1`. This
+  argument is optional.
+
+You can use it with key bindings like these:
+
+    -- Non-empty tag browsing
+    awful.key({ altkey }, "Left", function () lain.util.tag_view_nonempty(-1) end),
+    awful.key({ altkey }, "Right", function () lain.util.tag_view_nonempty(1) end),
+
+where `altkey = "Mod1"`.
+
+menu\_clients\_current\_tags
+----------------------------
+
+Similar to `awful.menu.clients`, but this menu only shows the clients
+of currently visible tags. Use it with a key binding like this:
+
+    awful.key({ "Mod1" }, "Tab",
+    function()
+        awful.menu.menu_keys.down = { "Down", "Alt_L", "Tab", "j" }
+        awful.menu.menu_keys.up = { "Up", "k" }
+        lain.util.menu_clients_current_tags({ width = 350 }, { keygrabber = true })
+    end),
+
+magnify\_client
+---------------
+
+Set a client to floating and resize it in the same way the "magnifier"
+layout does it. Place it on the "current" screen (derived from the mouse
+position). This allows you to magnify any client you wish, regardless of
+the currently used layout. Use it with a client keybinding like this:
+
+	clientkeys = awful.util.table.join(
+		...
+		awful.key({ modkey, "Control" }, "m", lain.util.magnify_client),
+		...
+	)
+
+If you want to "de-magnify" it, just retype the keybinding.
+
+niceborder\_{focus, unfocus}
+----------------------------
+
+By default, your `rc.lua` contains something like this:
+
+	client.connect_signal("focus", function(c) c.border_color = beautiful.border_focus end)
+	client.connect_signal("unfocus", function(c) c.border_color = beautiful.border_normal end)
+
+You can change it to this:
+
+	client.connect_signal("focus", lain.util.niceborder_focus(c))
+	client.connect_signal("unfocus", lain.util.niceborder_unfocus(c))
+
+Now, when a client is focused or unfocused, Awesome will look up its
+nice value in `/proc/<pid>/stat`. If it's less than 0, the client is
+classified as "high priority"; if it's greater than 0, the client is
+classified as "low priority". If it's equal to 0, nothing special
+happens.
+
+This requires to define additional colors in your `theme.lua`. For example:
+
+	theme.border_focus_highprio  = "#FF0000"
+	theme.border_normal_highprio = "#A03333"
+
+	theme.border_focus_lowprio   = "#3333FF"
+	theme.border_normal_lowprio  = "#333366"
