circbuf
=======
This repository provides the `circbuf` package. This provides a `Buffer` object
which is a circular (or ring) buffer. It has a fixed size, but can be written
to infinitely. Only the last `size` bytes are ever retained. The buffer implements
the `io.Writer` interface.
Documentation
=============
Full documentation can be found on [Godoc](http://godoc.org/github.com/armon/circbuf)
Usage
=====
The `circbuf` package is very easy to use:
```go
buf, _ := NewBuffer(6)
buf.Write([]byte("hello world"))
if string(buf.Bytes()) != " world" {
panic("should only have last 6 bytes!")
}
```
