https://github.com/BurntSushi/toml

+ TOML v0.4.0
+ MIT license
- doesn't preserve comments
- no tree structure available for recursion
- data is burried in multi-level tree of map[string]interface{}
+ preserves order in the metadata.Keys() [][]string, not very intuitive to use the metadata properly (TODO: link to example)

^ the best pkg out there, even though it's not perfect
