;;; Commentary:
;;;
;;; This is a wrapper for the linker.  Its purpose is to inspect the -L and
;;; -l switches passed to the linker, add corresponding -rpath arguments, and
;;; invoke the actual linker with this new set of arguments.
;;;
;;; The alternatives to this hack would be:
;;;
;;;   1. Using $LD_RUN_PATH.  However, that would tend to include more than
;;;      needed in the RPATH; for instance, given a package with `libfoo' as
;;;      an input, all its binaries would have libfoo in their RPATH,
;;;      regardless of whether they actually NEED it.
;;;
;;;   2. Use a GCC "lib" spec string such as `%{L*:-rpath %*}', which adds a
;;;      `-rpath LIBDIR' argument for each occurrence of `-L LIBDIR'.
;;;      However, this doesn't work when $LIBRARY_PATH is used, because the
;;;      additional `-L' switches are not matched by the above rule, because
;;;      the rule only matches explicit user-provided switches.  See
;;;      <http://gcc.gnu.org/ml/gcc-help/2012-09/msg00110.html> for details.

    (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.")

authors to pick a specific event loop, and without noticeable overhead.
Currently supported event loops are EV, Event, Glib/Gtk2, Tk, Qt,
@code{Event::Lib}, Irssi, @code{IO::Async} and POE (and thus also WxWidgets
and Prima).  It also comes with a very fast Pure Perl event loop that does
not rely on XS.")
