--      toml11 is a C++11 (or later) header-only toml parser/encoder depending
--      only on C++ standard library.
--
--      - It is compatible to the latest version of TOML v1.0.0.
--      - It is one of the most TOML standard compliant libraries, tested with
--        the language agnostic test suite for TOML parsers by BurntSushi.
--      - It shows highly informative error messages.
--      - It has configurable container. You can use any random-access containers
--        and key-value maps as backend containers.
--      - It optionally preserves comments without any overhead.
--      - It has configurable serializer that supports comments, inline tables,
--        literal strings and multiline strings.
--      - It supports user-defined type conversion from/into toml values.
--      - It correctly handles UTF-8 sequences, with or without BOM, both on posix
--        and Windows.
