Python 3 binding for LMDB Lightning Memory-Mapped Database

 Lightning Memory-Mapped Database (LMDB) is an ultra-fast, ultra-compact
 key-value embedded data store developed for the OpenLDAP Project. 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 (it
 is not limited to the size of physical RAM).
 .
 This package contains the 'lmdb' Python 3 extension module.
