    (synopsis "Lightweight C library that eases the writing of UNIX daemons")
    (description
     "Libdaemon is a lightweight C library that 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.

APIs like these are used in most daemon software available.  It is not that
simple to get it done right and code duplication is not a goal.")
