  66. <para>These notes are meant as an aid to reading and understanding
  67. some of the main code files forming the
  68. <application>gpsd</application> daemon and its support libraries. They
  69. are not a line-by-line explanation but only pick out the important (or
  70. unusual) aspects of the code.</para><para>They do not address the many
  71. programs that are used for test purposes, the individual device driver
  72. files or any of the supplied applications that use
  73. <application>gpsd</application>.</para>
  74. <para>This guide was written before the move to a JSON-based protocol
  75. and before AIS support was added. While the information on the rest of
  76. the code has been updated, the machinery relating to JSON and AIS
  77. is not yet documented here.</para>
