These bindings have been tested with Kyoto Cabinet version 1.2.46.
They are known not to work with 1.2.7 because of the absent
kcdbreplace() function call. Once Kyoto Cabinet is installed, building
the bindings should be a simple matter of running:

    goinstall -u -v bitbucket.org/ww/cabinet

Simple usage will be along the lines of,

    import (
        "bitbucket.org/ww/cabinet
    )

    ...

    kc := cabinet.New()
    err = kc.Open("some_db.kch", cabinet.KCOWRITER | cabinet.KCOCREATE)
    err = kc.Set([]byte("hello"), []byte("world"))
    world, err = kc.Get([]byte("hello"))
    err = kc.Close()
    kc.Del()

Obviously checking the relevant errors...

The API follows the Kyoto Cabinet C API closely, for some examples see
http://fallabs.com/kyotocabinet/api/

Most input and output variables are []byte and not string. This is because
Kyoto Cabinet is not particularly concerned with strings and it is possible
to use any byte array as either key or value. An example from the test
suite to read an integer out of the database:

    var n int64
    v, err = kc.Get([]byte("numbers"))
    binary.Read(bytes.NewBuffer(v), binary.BigEndian, &n)

Some functions have been added for convenience using Go. The Keys()
Values() and Items() on the cursor object return a channel over which
their results will be sent, for example. This probably obviates the need
for implementing the visitor-callback pattern when using Kyoto Cabinet
with Go.
