-Overview [![Build Status](https://travis-ci.org/magiconair/properties.svg?branch=master)](https://travis-ci.org/magiconair/properties)
-========
-
-#### Current version: 1.7.3
-
-properties is a Go library for reading and writing properties files.
-
-It supports reading from multiple files or URLs and Spring style recursive
-property expansion of expressions like `${key}` to their corresponding value.
-Value expressions can refer to other keys like in `${key}` or to environment
-variables like in `${USER}`.  Filenames can also contain environment variables
-like in `/home/${USER}/myapp.properties`.
-
-Properties can be decoded into structs, maps, arrays and values through
-struct tags.
-
-Comments and the order of keys are preserved. Comments can be modified
-and can be written to the output.
-
-The properties library supports both ISO-8859-1 and UTF-8 encoded data.
-
-Starting from version 1.3.0 the behavior of the MustXXX() functions is
-configurable by providing a custom `ErrorHandler` function. The default has
-changed from `panic` to `log.Fatal` but this is configurable and custom
-error handling functions can be provided. See the package documentation for
-details.
-
-Read the full documentation on [GoDoc](https://godoc.org/github.com/magiconair/properties)   [![GoDoc](https://godoc.org/github.com/magiconair/properties?status.png)](https://godoc.org/github.com/magiconair/properties)

-Getting Started
----------------
-
-```go
-import (
-	"flag"
-	"github.com/magiconair/properties"
-)
-
-func main() {
-	// init from a file
-	p := properties.MustLoadFile("${HOME}/config.properties", properties.UTF8)
-
-	// or multiple files
-	p = properties.MustLoadFiles([]string{
-			"${HOME}/config.properties",
-			"${HOME}/config-${USER}.properties",
-		}, properties.UTF8, true)
-
-	// or from a map
-	p = properties.LoadMap(map[string]string{"key": "value", "abc": "def"})
-
-	// or from a string
-	p = properties.MustLoadString("key=value\nabc=def")
-
-	// or from a URL
-	p = properties.MustLoadURL("http://host/path")
-
-	// or from multiple URLs
-	p = properties.MustLoadURL([]string{
-			"http://host/config",
-			"http://host/config-${USER}",
-		}, true)
-
-	// or from flags
-	p.MustFlag(flag.CommandLine)
-
-	// get values through getters
-	host := p.MustGetString("host")
-	port := p.GetInt("port", 8080)
-
-	// or through Decode
-	type Config struct {
-		Host    string        `properties:"host"`
-		Port    int           `properties:"port,default=9000"`
-		Accept  []string      `properties:"accept,default=image/png;image;gif"`
-		Timeout time.Duration `properties:"timeout,default=5s"`
-	}
-	var cfg Config
-	if err := p.Decode(&cfg); err != nil {
-		log.Fatal(err)
-	}
