+@uref{https://reuse.software, REUSE specification}, a set of recommendations
+for licensing Free Software projects.  REUSE makes it easy to declare the
+licenses under which your works are released, especially when reusing software
+from different projects released under different licenses.  It avoids reliance
+on fuzzy heuristicts and allows both legal experts and computers to understand
+how your project is licensed.  This allows generating a \"bill of materials\"
+for software.
+
+This tool downloads full license texts, adds copyright and license information
+to file headers, and contains a linter to identify problems.  There are other
+tools that have a lot more features and functionality surrounding the analysis
+and inspection of copyright and licenses in software projects.  This one is
+designed to be simple.")
