dirs-cli 0.1.0

A tiny low-level command line application that provides platform-specific standard locations of directories for config, cache and other data on Linux, Windows, macOS and Redox by leveraging the mechanisms defined by the XDG base/user directory specifications on Linux, the Known Folder API on Windows, and the Standard Directory guidelines on macOS.
