* Introduction

  This software is an implementation of the Precision Time Protocol
  (PTP) according to IEEE standard 1588 for Linux. The dual design
  goals are to provide a robust implementation of the standard and to
  use the most relevant and modern Application Programming Interfaces
  (API) offered by the Linux kernel. Supporting legacy APIs and other
  platforms is not a goal.

* License

  GNU General Public License. See the file, COPYING, for details of
  the license terms.

* Goals and Features

  - Supports hardware and software time stamping via the Linux
    SO_TIMESTAMPING socket option.

  - Supports the Linux PTP Hardware Clock (PHC) subsystem by using the
    clock_gettime family of calls, including the new clock_adjtimex
    system call.

  - Implements Boundary Clock (BC) and Ordinary Clock (OC).

  - Transport over UDP/IPv4, UDP/IPv6, and raw Ethernet (Layer 2).

  - Modular design allowing painless addition of new transports and
    clock servos.
