+Package ansi is a small, fast library to create ANSI colored strings and codes.
+
+Installation
+
+    # this installs the color viewer and the package
+    go get -u github.com/mgutz/ansi/cmd/ansi-mgutz
+
+Example
+
+	// colorize a string, SLOW
+	msg := ansi.Color("foo", "red+b:white")
+
+	// create a closure to avoid recalculating ANSI code compilation
+	phosphorize := ansi.ColorFunc("green+h:black")
+	msg = phosphorize("Bring back the 80s!")
+	msg2 := phospohorize("Look, I'm a CRT!")
+
+	// cache escape codes and build strings manually
+	lime := ansi.ColorCode("green+h:black")
+	reset := ansi.ColorCode("reset")
+
+	fmt.Println(lime, "Bring back the 80s!", reset)
+
+Other examples
+
+	Color(s, "red")            // red
+	Color(s, "red+b")          // red bold
+	Color(s, "red+B")          // red blinking
+	Color(s, "red+u")          // red underline
+	Color(s, "red+bh")         // red bold bright
+	Color(s, "red:white")      // red on white
+	Color(s, "red+b:white+h")  // red bold on white bright
+	Color(s, "red+B:white+h")  // red blink on white bright
