//! The _dirs-next_ crate is
//!
//! - a tiny library with a minimal API (16 functions)
//! - that provides the platform-specific, user-accessible locations
//! - for finding and storing configuration, cache and other data
//! - on Linux, Redox, Windows (≥ Vista) and macOS.
//!
//! The library provides the location of these directories by leveraging the mechanisms defined by
//!
//! - the [XDG base directory](https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html) and the [XDG user directory](https://www.freedesktop.org/wiki/Software/xdg-user-dirs/) specifications on Linux,
//! - the [Known Folder](https://msdn.microsoft.com/en-us/library/windows/desktop/bb776911(v=vs.85).aspx) system on Windows, and
//! - the [Standard Directories](https://developer.apple.com/library/content/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html#//apple_ref/doc/uid/TP40010672-CH2-SW6) on macOS.
