+    h := log.CallerStackHandler("%+v", log.StdoutHandler)
-	log.Root().SetHandler(h)

@@ -150,50 +155,50 @@ This package provides a simple type to annotate a logging operation that you wan
 lazily, just when it is about to be logged, so that it would not be evaluated if an upstream Handler
 filters it out. Just wrap any function which takes no arguments with the log.Lazy type. For example:
 
-	func factorRSAKey() (factors []int) {
+    func factorRSAKey() (factors []int) {
-	    // return the factors of a very large number
+        // return the factors of a very large number
-	}
+    }
 
-	log.Debug("factors", log.Lazy{factorRSAKey})
+    log.Debug("factors", log.Lazy{factorRSAKey})
 
 If this message is not logged for any reason (like logging at the Error level), then
 factorRSAKey is never evaluated.
 
-# Dynamic context values
+Dynamic context values
 
 The same log.Lazy mechanism can be used to attach context to a logger which you want to be
 evaluated when the message is logged, but not when the logger is created. For example, let's imagine
 a game where you have Player objects:
 
-	type Player struct {
+    type Player struct {
-	    name string
+        name string
-	    alive bool
+        alive bool
-	    log.Logger
+        log.Logger
-	}
+    }
 
 You always want to log a player's name and whether they're alive or dead, so when you create the player
 object, you might do:
 
-	p := &Player{name: name, alive: true}
+    p := &Player{name: name, alive: true}
-	p.Logger = log.New("name", p.name, "alive", p.alive)
+    p.Logger = log.New("name", p.name, "alive", p.alive)
 
 Only now, even after a player has died, the logger will still report they are alive because the logging
 context is evaluated when the logger was created. By using the Lazy wrapper, we can defer the evaluation
 of whether the player is alive or not to each log message, so that the log records will reflect the player's
 current state no matter when the log message is written:
 
-	p := &Player{name: name, alive: true}
+    p := &Player{name: name, alive: true}
-	isAlive := func() bool { return p.alive }
+    isAlive := func() bool { return p.alive }
-	player.Logger = log.New("name", p.name, "alive", log.Lazy{isAlive})
+    player.Logger = log.New("name", p.name, "alive", log.Lazy{isAlive})

-# Library Use
+Library Use
 
 log15 is intended to be useful for library authors as a way to provide configurable logging to
 users of their library. Best practice for use in a library is to always disable all output for your logger
 by default and to provide a public Logger instance that consumers of your library can configure. Like so:
 
-	package yourlib
+    package yourlib
 
-	import "github.com/inconshreveable/log15"
+    import "github.com/inconshreveable/log15"

+    var Log = log.New()
 
-	func init() {
+    func init() {
-	    Log.SetHandler(log.DiscardHandler())
+        Log.SetHandler(log.DiscardHandler())
-	}
+    }
 
 Users of your library may then enable it if they like:
 
-	import "github.com/inconshreveable/log15"
+    import "github.com/inconshreveable/log15"
-	import "example.com/yourlib"

-	}
+    }
 
-# Best practices attaching logger context
+Best practices attaching logger context
 
 The ability to attach context to a logger is a powerful one. Where should you do it and why?
 I favor embedding a Logger directly into any persistent object in my application and adding
 unique, tracing context keys to it. For instance, imagine I am writing a web browser:
 
-	type Tab struct {
+    type Tab struct {
-	    url string
+        url string
-	    render *RenderingContext
+        render *RenderingContext
-	    // ...
+        // ...
 
-	    Logger
+        Logger
-	}
+    }
 
-	func NewTab(url string) *Tab {
+    func NewTab(url string) *Tab {
-	    return &Tab {
+        return &Tab {
-	        // ...
+            // ...
-	        url: url,
+            url: url,
 
-	        Logger: log.New("url", url),
+            Logger: log.New("url", url),
-	    }
+        }
-	}
+    }
 
 When a new tab is created, I assign a logger to it with the url of
 the tab as context so it can easily be traced through the logs.
 Now, whenever we perform any operation with the tab, we'll log with its
 embedded logger and it will include the tab title automatically:
 
-	tab.Debug("moved position", "idx", tab.idx)
+    tab.Debug("moved position", "idx", tab.idx)
 
 There's only one problem. What if the tab url changes? We could

+        t.Logger = log.New("id", logext.RandId(8), "url", log.Lazy{t.getUrl})
-	return t
+        return t
 
 Now we'll have a unique traceable identifier even across loading new urls, but
 we'll still be able to see the tab's current url in the log messages.
 
-# Must

 For all Handler functions which can return an error, there is a version of that
 function which will return no error but panics on failure. They are all available
 on the Must object. For example:
