-## TOML parser and encoder for Go with reflection
-
-TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
-reflection interface similar to Go's standard library `json` and `xml`
-packages. This package also supports the `encoding.TextUnmarshaler` and
-`encoding.TextMarshaler` interfaces so that you can define custom data
-representations. (There is an example of this below.)
-
-Spec: https://github.com/mojombo/toml
-
-Compatible with TOML version
-[v0.2.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.2.0.md)
-
-Documentation: http://godoc.org/github.com/BurntSushi/toml
-
-Installation:
-
-```bash
-go get github.com/BurntSushi/toml
-```
-
-Try the toml validator:
-
-```bash
-go get github.com/BurntSushi/toml/cmd/tomlv
-tomlv some-toml-file.toml
-```
-
-[![Build status](https://api.travis-ci.org/BurntSushi/toml.png)](https://travis-ci.org/BurntSushi/toml)
-
-
-### Testing
-
-This package passes all tests in
-[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
-and the encoder.
-
-### Examples
-
-This package works similarly to how the Go standard library handles `XML`
-and `JSON`. Namely, data is loaded into Go values via reflection.
-
-For the simplest example, consider some TOML file as just a list of keys
-and values:
-
-```toml
-Age = 25
-Cats = [ "Cauchy", "Plato" ]
-Pi = 3.14
-Perfection = [ 6, 28, 496, 8128 ]
-DOB = 1987-07-05T05:45:00Z
-```
-
-Which could be defined in Go as:
-
-```go
-type Config struct {
- Age int
- Cats []string
- Pi float64
- Perfection []int
- DOB time.Time // requires `import time`
-}
-```
-
-And then decoded with:
-
-```go
-var conf Config
-if _, err := toml.Decode(tomlData, &conf); err != nil {
- // handle error
-}
-```
-
-You can also use struct tags if your struct field name doesn't map to a TOML
-key value directly:
-
-```toml
-some_key_NAME = "wat"
-```
-
-```go
-type TOML struct {
- ObscureKey string `toml:"some_key_NAME"`
-}
-```
-
-### Using the `encoding.TextUnmarshaler` interface
-
-Here's an example that automatically parses duration strings into
-`time.Duration` values:
-
-```toml
-[[song]]
-name = "Thunder Road"
-duration = "4m49s"
-
-[[song]]
-name = "Stairway to Heaven"
-duration = "8m03s"
-```
-
-Which can be decoded with:
-
-```go
-type song struct {
- Name string
- Duration duration
-}
-type songs struct {
- Song []song
-}
-var favorites songs
-if _, err := toml.Decode(blob, &favorites); err != nil {
- log.Fatal(err)
-}
-
-for _, s := range favorites.Song {
- fmt.Printf("%s (%s)\n", s.Name, s.Duration)
-}
-```
-
-And you'll also need a `duration` type that satisfies the
-`encoding.TextUnmarshaler` interface:
-
-```go
-type duration struct {
- time.Duration
-}
-
-func (d *duration) UnmarshalText(text []byte) error {
- var err error
- d.Duration, err = time.ParseDuration(string(text))
- return err
-}
-```
-
-### More complex usage
-
-Here's an example of how to load the example from the official spec page:
-
-```toml
-# This is a TOML document. Boom.
-
-title = "TOML Example"
-
-[owner]
-name = "Tom Preston-Werner"
-organization = "GitHub"
-bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
-dob = 1979-05-27T07:32:00Z # First class dates? Why not?
-
-[database]
-server = "192.168.1.1"
-ports = [ 8001, 8001, 8002 ]
-connection_max = 5000
-enabled = true
-
-[servers]
-
- # You can indent as you please. Tabs or spaces. TOML don't care.
- [servers.alpha]
- ip = "10.0.0.1"
- dc = "eqdc10"
-
- [servers.beta]
- ip = "10.0.0.2"
- dc = "eqdc10"
-
-[clients]
-data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
-
-# Line breaks are OK when inside arrays
-hosts = [
- "alpha",
- "omega"
-]
-```
-
-And the corresponding Go types are:
-
-```go
-type tomlConfig struct {
- Title string
- Owner ownerInfo
- DB database `toml:"database"`
- Servers map[string]server
- Clients clients
-}
-
-type ownerInfo struct {
- Name string
- Org string `toml:"organization"`
- Bio string
- DOB time.Time
-}
-
-type database struct {
- Server string
- Ports []int
- ConnMax int `toml:"connection_max"`
- Enabled bool
-}
-
-type server struct {
- IP string
- DC string
-}
-
-type clients struct {
- Data [][]interface{}
- Hosts []string
-}
-```
-
-Note that a case insensitive match will be tried if an exact match can't be
-found.
-
-A working example of the above can be found in `_examples/example.{go,toml}`.

-// (floats, strings, integers, booleans and datetimes) will be converted to

-// Unmarshaler example for a demonstration with time duration strings.
-//
-// Key mapping
-//
-// TOML keys can map to either keys in a Go map or field names in a Go

-//
-// The mapping between TOML values and Go values is loose. That is, there

-// there may be parts of your representation that do not correspond to
-// TOML values. This loose mapping can be made stricter by using the IsDefined

-/*
-Package toml provides facilities for decoding and encoding TOML configuration
-files via reflection. There is also support for delaying decoding with
-the Primitive type, and querying the set of keys in a TOML document with the
-MetaData type.
-
-The specification implemented: https://github.com/mojombo/toml
-
-The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
-whether a file is a valid TOML document. It can also be used to print the
-type of each key in a TOML document.
-
-Testing
-
-There are two important types of tests used for this package. The first is
-contained inside '*_test.go' files and uses the standard Go unit testing
-framework. These tests are primarily devoted to holistically testing the
-decoder and encoder.
-
-The second type of testing is used to verify the implementation's adherence
-to the TOML specification. These tests have been factored into their own
-project: https://github.com/BurntSushi/toml-test
-
-The reason the tests are in a separate project is so that they can be used by
-any implementation of TOML. Namely, it is language agnostic.
