+//! The _dirs_ 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.

+///
+/// The returned value depends on the operating system and is either a `Some`, containing a value from the following table, or a `None`.
+///
+/// |Platform | Value                | Example        |
+/// | ------- | -------------------- | -------------- |
+/// | Linux   | `$HOME`              | /home/alice    |
+/// | macOS   | `$HOME`              | /Users/Alice   |
+/// | Windows | `{FOLDERID_Profile}` | C:\Users\Alice |
+///
+/// ### Linux and macOS:
+///
+/// - Use `$HOME` if it is set and not empty.
+/// - If `$HOME` is not set or empty, then the function `getpwuid_r` is used to determine
+///   the home directory of the current user.
+/// - If `getpwuid_r` lacks an entry for the current user id or the home directory field is empty,
+///   then the function returns `None`.
+///
+/// ### Windows:
+///
+/// This function retrieves the user profile folder using `SHGetKnownFolderPath`.
+///
+/// All the examples on this page mentioning `$HOME` use this behavior.
+///
+/// _Note:_ This function's behavior differs from [`std::env::home_dir`],
+/// which works incorrectly on Linux, macOS and Windows.
