  41     (description
  42      "libdaemon is a lightweight C library that eases the writing of UNIX
  43 daemons. It consists of the following parts:
  44
  45   • A wrapper around fork() which does the correct daemonization procedure of
  46     a process
  47
  48   • A wrapper around syslog() for simpler and compatible log output to Syslog
  49     or STDERR
  50
  51   • An API for writing PID files
  52
  53   • An API for serializing UNIX signals into a pipe for usage with select() or
  54     poll()
  55
  56   • An API for running subprocesses with STDOUT and STDERR redirected to
  57     syslog.
  58
  59 APIs like these are used in most daemon software available. It is not that
  60 simple to get it done right and code duplication is not a goal.")
