= ISC DHCP Server API
This package controls the process (starts, stops) and the configuration file of `isc-dhcp-server`.
You can use [github.com/xaionaro-go/iscDhcp/cfg](https://github.com/xaionaro-go/iscDhcp/tree/master/cfg) as just a config parser/generator.
UPD: Seems the parser/generator is useless, because there's another (better) project: [github.com/sayotte/iscdhcp](https://github.com/sayotte/iscdhcp)
```
package main
import (
"encoding/json"
"github.com/xaionaro-go/iscDhcp/cfg"
"os"
)
func main() {
cfg := cfg.NewConfig()
err := cfg.LoadFrom("/etc/dhcp/dhcpd.conf")
if err != nil {
panic(err)
}
jsonEncoder := json.NewEncoder(os.Stderr)
jsonEncoder.SetIndent("", " ")
jsonEncoder.Encode(cfg)
}
