-# globalconf
-
-[![Build Status](https://travis-ci.org/rakyll/globalconf.png?branch=master)](https://travis-ci.org/rakyll/globalconf)
-
-Effortlessly persist/retrieve flags of your Golang programs. If you need global configuration instead of requiring user always to set command line flags, you are looking at the right package. `globalconf` allows your users to not only provide flags, but config files and environment variables as well.
-
-## Usage
-
-~~~ go
-import "github.com/rakyll/globalconf"
-~~~
-
-### Loading a config file
-
-By default, globalconf provides you a config file under `~/.config/<yourappname>/config.ini`.
-
-~~~ go
-globalconf.New("appname") // loads from ~/.config/<appname>/config.ini
-~~~
-
-If you don't prefer the default location you can load from a specified path as well.
-
-~~~ go
-globalconf.NewWithOptions(&globalconf.Options{
-	Filename: "/path/to/config/file",
-})
-~~~
-
-You may like to override configuration with env variables. See "Environment variables" header to see how to it works.
-
-~~~ go
-globalconf.NewWithOptions(&globalconf.Options{
-	Filename:  "/path/to/config/file",
-	EnvPrefix: "APPCONF_",
-})
-~~~
-
-### Parsing flag values
-
-`globalconf` populates flags with data in the config file if they are not already set.
-
-~~~ go
-var (
-	flagName    = flag.String("name", "", "Name of the person.")
-	flagAddress = flag.String("addr", "", "Address of the person.")
-)
-~~~
-	
-Assume the configuration file to be loaded contains the following lines.
-
-	name = Burcu
-	addr = Brandschenkestrasse 110, 8002
-
-And your program is being started, `$ myapp -name=Jane`
-~~~ go
-conf, err := globalconf.New("myapp")
-conf.ParseAll()
-~~~
-
-`*flagName` is going to be equal to `Jane`, whereas `*flagAddress` is `Brandschenkestrasse 110, 8002`, what is provided in the configuration file.
-
-### Custom flag sets
-
-Custom flagsets are supported, but required registration before parse is done. The default flagset `flag.CommandLine` is automatically registered.
-
-~~~ go
-globalconf.Register("termopts", termOptsFlagSet)
-conf.ParseAll() // parses command line and all registered flag sets
-~~~
-
-Custom flagset values should be provided in their own segment. Getting back to the sample ini config file, termopts values will have their own segment.
-
-	name = Burcu
-	addr = Brandschenkestrasse 110, 8002
-	
-	[termopts]
-	color = true
-	background = ff0000
-
-### Environment variables
-
-If an EnvPrefix is provided, environment variables will take precedence over values in the configuration file.
-Set the `EnvPrefix` option when calling `globalconf.NewWithOptions`.
-An `EnvPrefix` will only be used if it is a non-empty string.
-Command line flags will override the environment variables.
-
-~~~ go
-opts := globalconf.Options{
-	EnvPrefix: "MYAPP_",
-	Filename:  "/path/to/config",
-}
-conf, err := globalconf.NewWithOptions(&opts)
-conf.ParseAll()
-~~~
-
-With environment variables:
-
-	APPCONF_NAME = Burcu
-
-and configuration:
-
-	name = Jane
-	addr = Brandschenkestrasse 110, 8002
-
-`name` will be set to "burcu" and `addr` will be set to "Brandschenkestrasse 110, 8002".
-
-### Modifying stored flags
-
-Modifications are persisted as long as you set a new flag and your GlobalConf
-object was configured with a filename.
-
-~~~ go
-f := &flag.Flag{Name: "name", Value: val}
-conf.Set("", f) // if you are modifying a command line flag
-
-f := &flag.Flag{Name: "color", Value: val}
-conf.Set("termopts", color) // if you are modifying a custom flag set flag
-~~~
-
-### Deleting stored flags
-
-Like Set, Deletions are persisted as long as you delete a flag's value and your
-GlobalConf object was configured with a filename.
-
-~~~ go
-conf.Delete("", "name") // removes command line flag "name"s value from config
-conf.Delete("termopts", "color") // removes "color"s value from the custom flag set
-~~~
