+  This library provide an easy interface to the black magic that can be done
+  on Unix domain sockets, like passing file descriptors from one process to
+  another.
+
+  Programs that uses this library should include the ancillary.h header file.
+  Nothing else is required.
+
+  All functions of this library require the following header:
+
+	#include <ancillary.h>
+
+  At this time, the only ancillary data defined by the Single Unix
+  Specification (v3) is file descriptors.
+
+Passing file descriptors
+
+	int ancil_send_fd(socket, file_descriptor)
+	  int socket: the Unix socket
+	  int file_descriptor: the file descriptor
+	  Return value: 0 for success, -1 for failure.
+
+  Sends one file descriptor on a socket.
+  In case of failure, errno is set; the possible values are the ones of the
+  sendmsg(2) system call.
+
+
+	int ancil_recv_fd(socket, file_descriptor)
+	  int socket: the Unix socket
+	  int *file_descriptor: pointer to the returned file descriptor
+	  Return value: 0 for success, -1 for failure
+
+  Receives one file descriptor from a socket.
+  In case of success, the file descriptor is stored in the integer pointed
+  to by file_descriptor.
+  In case of failure, errno is set; the possible values are the ones of the
+  recvmsg(2) system call.
+  The behavior is undefined if the recv_fd does not match a send_fd* on the
+  other side.
+
+
+	int ancil_send_fds(socket, file_descriptors, num_file_descriptors)
+	  int socket: the Unix socket
+	  const int *file_descriptors: array of file descriptors
+	  unsigned num_file_descriptors: number of file descriptors
+	  Return value: 0 for success, -1 for failure
+
+  Sends several file descriptors on a socket.
+  In case of failure, errno is set; the possible values are the ones of the
+  sendmsg(2) system call.
+  The maximum number of file descriptors that can be sent using this
+  function is ANCIL_MAX_N_FDS; the behavior is undefined in case of
+  overflow, probably a stack corruption.
+
+
+	int ancil_recv_fds(socket, file_descriptors, num_file_descriptors)
+	  int socket: the Unix socket
+	  int *file_descriptors: return array of file descriptors
+	  unsigned num_file_descriptors: number of file descriptors
+	  Return value: number of received fd for success, -1 for failure
+
+  Receives several file descriptors from a socket, no more than
+  num_file_descriptors.

+	  const int *fds: array of file descriptors
+	  unsigned num: number of file descriptors
+	  void *buffer: buffer to hold the system data structures
+	  Return value: 0 for success, -1 for failure
+
+  Sends several file descriptors on a socket.
+  In case of failure, errno is set; the possible values are the ones of the
+  sendmsg(2) system call.
+  The buffer argument must point to a memory area large enough to hold the
+  system data structures, see ANCIL_FD_BUFFER.
+
+

+  num_file_descriptors.
+  The buffer argument must point to a memory area large enough to hold the
+  system data structures, see ANCIL_FD_BUFFER.
+
+
+	ANCIL_MAX_N_FDS
+
+  Maximum number of file descriptors that can be sent with the sent_fds and
+  recv_fds functions. If you have to send more at once, use the
+  *_with_buffer versions. The value is enough to send "quite a few" file
+  descriptors.
+
+
+	ANCIL_FD_BUFFER(n)
+	  int n: number of file descriptors
+
+  Expands to a structure data type large enough to hold the system data
+  structures for n file descriptors. So the address of a variable declared
+  of type ANCIL_FD_BUFFER(n) is suitable as the buffer argument for
+  *_with_buffer on n file descriptors.
+  To use this macro, you need <sys/types.h> and <sys/socket.h>. Bevare: with
+  Solaris, the _XPG4_2 macro must be defined before sys/socket is included.

+Tuning the compilation
+
+  This library is designed to be included in projects, not installed in
