+Dist
+-------
+
+Provide ``dist`` and ``distcheck`` targets similar to
+autoconf/automake functionality.
+
+The ``dist`` target creates tarballs of the project in ``.tar.gz`` and
+``.tar.xz`` formats.
+
+The ``distcheck`` target extracts one of created tarballs, builds the
+software using its defaults, and runs the tests.
+
+Both targets use Unix shell commands.
+
+The Dist target takes one argument, the file name (before the extension).
+
+The ``distcheck`` target creates (and removes) ``${ARCHIVE_NAME}-build``
+and ``${ARCHIVE_NAME}-dest``.
