 know-how behind this software, and nothing else is even remotely comparable.

   H3: back-ldbm
   
   back-ldbm was both slow and unreliable. Its byzantine indexing code was
   prone to spontaneous corruption, as were the underlying database libraries
   that were commonly used (e.g. GDBM or NDBM). back-bdb and back-hdb are
   superior in every aspect, with simplified indexing to avoid index corruption,
   fine-grained locking for greater concurrency, hierarchical caching for
   greater performance, streamlined on-disk format for greater efficiency
   and portability, and full transaction support for greater reliability.
