+/// `Directory Environment` Setup for managing common directory resources
+///
+/// This Setup registers commonly used directory resources into the program's
+/// resource store. It provides the current working directory, the executable's
+/// directory, the user's home directory, and the system's temporary directory,
+/// so that these paths can be retrieved from the resource store without
+/// recomputing them each time.
+///
+/// # Usage
+///
+/// This Setup can be registered using the
+/// [`Program`](https://docs.rs/mingling/latest/mingling/struct.Program.html)
+/// `with_setup` method, for example:
+///
+/// ```rust
+/// # use mingling::MockProgramCollect as ThisProgram;
+/// use mingling::Program;
+/// use mingling::setup::DirectoryEnvironmentSetup;
+///
+/// let mut program = Program::<ThisProgram>::new();
+/// program.with_setup(DirectoryEnvironmentSetup);
+/// ```
+///
+/// # Behavior
+///
+/// - Registers an [`ResCurrentDir`] resource containing the current working
+///   directory.
+/// - Registers an [`ResCurrentExe`] resource containing the directory of the
+///   currently running executable.
+/// - Registers an [`ResHomeDir`] resource containing the user's home directory.
+/// - Registers an [`ResTempDir`] resource containing the system's temporary
+///   directory.
+///
+/// # Notes
+///
+/// - All directory values are resolved at setup time and stored in the
+///   resource store.
+/// - These resources can be retrieved later using the program's `resource`
+///   accessor with the corresponding resource type.
