+//! Filesystem paths in Windows are a total mess. This crate normalizes paths to the most
+//! compatible (but still correct) format, so that you don't have to worry about the mess.
+//!
+//! In Windows the regular/legacy paths (`C:\foo`) are supported by all programs, but have
+//! lots of bizarre restrictions for backwards compatibility with MS-DOS.
+//!
+//! And there are Windows NT UNC paths (`\\?\C:\foo`), which are more robust and with fewer
+//! gotchas, but are rarely supported by Windows programs. Even Microsoft's own!
+//!
+//! This crate converts paths to legacy format whenever possible, but leaves UNC paths as-is
+//! when they can't be unambiguously expressed in a simpler way. This allows legacy programs
+//! to access all paths they can possibly access, and UNC-aware programs to access all paths.
+//!
+//! On non-Windows platforms these functions leave paths unmodified, so it's safe to use them
+//! unconditionally for all platforms.
+//!
+//! Parsing is based on https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx
+//!
+//! [Project homepage](https://crates.rs/crates/dunce).
