Libdaemon

libdaemon is a lightweight C library which eases the writing of UNIX daemons.
It consists of the following parts:
* A wrapper around fork() which does the correct daemonization
  procedure of a process
* A wrapper around syslog() for simpler and compatible log output to
  Syslog or STDERR
* An API for writing PID files
* An API for serializing UNIX signals into a pipe for usage with
  select() or poll()
* An API for running subprocesses with STDOUT and STDERR redirected
  to syslog.
