This is a library which has simple functionality to make lisp process daemonize on unix like platform.
## Usage
Currently only `daemon:daemonize` and `daemon:exit` function are exported.
so just a simple example is good enough to show the idea of this library.
```
(daemon:daemonize :exit-parent t)
(with-open-file (out #P "/tmp/daemonlog" :direction :output :if-exists :supersede)
(format out "~A ~A~%~A~%"
(lisp-implementation-type)
(lisp-implementation-version)
(daemon::getpid)))
(sleep 90)
(daemon:exit)
```
then you can see the effect by the command below.
```
ps axo user,pid,ppid,command
```
