Delta compression algorithm written in Go
===
Fossil achieves efficient storage and low-bandwidth synchronization through the
use of delta-compression. Instead of storing or transmitting the complete
content of an artifact, fossil stores or transmits only the changes relative to
a related artifact.

### Install
```
$ go get -u github.com/shadowspore/fossil-delta
```
### Example
```go
package main
import (
"fmt"
fdelta "github.com/shadowspore/fossil-delta"
)
func main() {
origin := []byte("abcdefghijklmnopqrstuvwxyz1234567890")
target := []byte("abcdefghijklmnopqrstuvwxyz0987654321")
// Create delta
delta := fdelta.Create(origin, target)
// Create target by patching origin with delta
patched, err := fdelta.Apply(origin, delta)
if err != nil {
panic(err)
}
fmt.Printf("Origin: `%s`\n", origin)
fmt.Printf("Target: `%s`\n", target)
fmt.Printf("Delta : `%s`\n", delta)
fmt.Printf("Patch : `%s`\n", patched)
}
```
