    <para>
      The <application>lmdb</application> package is a fast, compact, key-value
      embedded data store.  It uses memory-mapped files, so it has the read
      performance of a pure in-memory database while still offering the
      persistence of standard disk-based databases, and is only limited to the
      size of the virtual address space

    <!--para>
      <command>sed ... prefix ... Makefile</command>: The Makefile creates the
      man pages directory during install if it is not present.
      This fixes the directory location.
    </para-->

    <para>
      <command>sed ... liblmdb.a ... Makefile</command>: The package executables
      use a static library so it must be created.  This command suppresses installation
      of the static library.
