+    "NFiles is a Common Lisp library to help manage file persistence and
+loading, in particular user-centric files like configuration files.  It boasts
+the following features:
+
+@itemize
+@item Dynamic and customizable path expansion.
+
+@item Extensible serialization and deserialization.
+
+@item Cached reads and writes.  When a file object expands to the same path as
+another one, a read or write on it won’t do anything in case there was no
+change since last write.
+
+@item (Experimental!) On-the-fly PGP encryption.
+
+@item Profile support.
+
+@item On read error, existing files are backed up.
+
+@item On write error, no file is written to disk, the existing file is preserved.
+@end itemize\n")
