+mtredisalize
+------------
+
+A simple server that offers a TCP/Redis interface for LevelDB and SQLite3 based
+Minetest worlds.
+
+Disclaimer:
+
+    !!! This software is very young and not well tested! Use at your own risk.
+    !!! If you want to try it out backup your original databases, please!
+    !!! Motivation:
+
+The Redis backend is nice if you want to do use the backend for other
+purposes than backing the Minetest server at the same time, e.g. do
+some mapping. On the other hand the Redis is by its nature as an in-memory
+database quiet a memory hungry beast. This is fine if you have smaller
+worlds or a lot of hardware to throw on it.
+
+The other two backends (SQLite3 and LevelDB) are embedded database
+which are hard to work with if you want to access them from another
+process.
+
+The idea of mtredisalize is to wrap a server around the embedded databases
+and offer a TCP Redis interface a Minetest server and other
+processes can connect with. 
+
+   Beware! This is _not_ a fully featured Redis server with all of its commands.
+   Only the subset of Redis commands is implemented which is needed to run Minetes
+   on top of it.
+
+To build mtredisalize a Go 1.x (x >= 1) enviroment is needed. By now
+it is only tested on Ubuntu 14.04/amd64.
+
+Obtain:
+
+  $ go get bitbucket.org/s_l_teichmann/mtredisalize
+
+Development:
+
+  $ go get github.com/mattn/go-sqlite3
+  $ go get github.com/jmhodges/levigo
+  $ hg clone  https://s_l_teichmann@bitbucket.org/s_l_teichmann/mtredisalize
+  $ go build
+
+Usage:
+
+  $ mtredisalize [<options>] /path/to/database
+
+  with options:
+    -cache=32: cache size in MB # Cache size for LevelDB
+    -driver="leveldb": type of database (leveldb, sqlite)
+    -host="": host to bind
+    -port=6379: port to bind
+
+To use mtredisalize with your particular world you have to modify the
+world.mt of the world.
+
+You have to set the backend to redis and redis_address, the redis_port and the
+redis_hash to match the start options of mtredisalize. The hash is ignored by
+mtredisalize but has to be in the world.mt to make Minetest happy.
+redis_port defaults to 6379.
+
+  gameid = minetest
+  backend = redis
+  redis_address = localhost
+  redis_port = 6380
+  redis_hash = IGNORED
+
+would e.g. matches:
+
+   $ mtredisalize --port=6380 --host=localhost ..
+
+The mandatory path is the path to the database file: map.sqlite in case
+of SQLite3 and the directoy map.db in case of LevelDB right beside the world.mt file.
