+ (description
+ "The @dfn{Lightning Memory-Mapped Database} (LMDB) is a high-performance
+transactional database. Unlike more complex relational databases, LMDB handles
+only key-value pairs (stored as arbitrary byte arrays) and relies on the
+underlying operating system for caching and locking, keeping the code small and
+simple.
+The use of ‘zero-copy’ memory-mapped files combines the persistence of classic
+disk-based databases with high read performance that scales linearly over
+multiple cores. The size of each database is limited only by the size of the
+virtual address space — not physical RAM.")
