var daemon = require('daemonspawn')

var proc = daemon.spawn(cmd, opts)

spawns a daemonized process by spawning cmd with opts using npm-execspawn, which has the same interface as child_process.spawn

returns proc, the child process. you need to remember proc.pid in order to use the other methods, usually people save it to a file, but any method will work.

daemon.status(pid, cb)

checks if pid is running, calls cb with (error, running) where running is a boolean

daemon.kill(pid, cb)

SIGKILLs the pid, calls cb with (err)
