  67     (description
  68      "Libdaemon is a lightweight C library that eases the writing of UNIX
  69 daemons.  It consists of the following parts:
  70
  71   • A wrapper around fork() which does the correct daemonization procedure of
  72     a process
  73
  74   • A wrapper around syslog() for simpler and compatible log output to Syslog
  75     or STDERR
  76
  77   • An API for writing PID files
  78
  79   • An API for serializing UNIX signals into a pipe for usage with select() or
  80     poll()
  81
  82   • An API for running subprocesses with STDOUT and STDERR redirected to
  83     syslog.
  84
  85 APIs like these are used in most daemon software available.  It is not that
  86 simple to get it done right and code duplication is not a goal.")
