How to compile:
- Put the lds* files under the db directory.
- Put the env_lds.cc under the util directory.
- Compile LevelDB.
How to use:
When open a database, the user should pass a device name such as /dev/sdh or /dev/sdh1 to the LevelDB, instead of passing a directory. A pre-allocated file is also legal to be passed but not fully supported.
