levigo is a Go wrapper for LevelDB.
The API has been godoc'ed and is available on the web.

You'll need the shared library build of LevelDB installed on your machine. The current LevelDB will build it by default.
Now, if you build LevelDB and put the shared library and headers in one of the standard places for your OS, you'll be able to simply run:
go get github.com/jmhodges/levigo
But, suppose you put the shared LevelDB library somewhere weird like /path/to/lib and the headers were installed in /path/to/include. To install levigo remotely, you'll run:
CGO_CFLAGS="-I/path/to/leveldb/include" CGO_LDFLAGS="-L/path/to/lib" go get github.com/jmhodges/levigo
and there you go.
Of course, the rules apply locally with go build instead of go get.
Comparators and WriteBatch iterators must be written in C in your own library. This is slightly better when you realize you'll have the LevelDB C API available to your in your client package by including levigo and its build.
