+across many systems, working with Unicode strings, cryptographic computation,
+and much more.  The code is intended to be shared at the level of source
+files, rather than being a standalone library that is distributed, built, and
+installed.  The included @command{gnulib-tool} script helps with using Gnulib
+code in other packages.  Gnulib also includes copies of licensing and
+maintenance-related files, for convenience.")
