 nghttp2 project was started as a fork of spdylay project [1].  Both
 projects were started by Tatsuhiro Tsujikawa, who is still the main
 author of these projects.  Meanwhile, we have many contributions, and
 we are not here without them.  We sincerely thank you to all who made
 a contribution.  Here is the all individuals/organizations who
 contributed to nghttp2 and spdylay project at which we forked.  These
 names are retrieved from git commit log.  If you have made a
 contribution, but you are missing in the list, please let us know via

 nghttp2 Documentation
 =====================
 The documentation of nghttp2 is generated using Sphinx.  This
 directory contains the source files to be processed by Sphinx.  The
 source file for API reference is generated using a script called
 ``mkapiref.py`` from the nghttp2 C source code.
 Generating API reference
 ------------------------
 As described earlier, we use ``mkapiref.py`` to generate rst formatted
 text of API reference from C source code.  The ``mkapiref.py`` is not
 so flexible and it requires that C source code is formatted in rather
 strict rules.
 To generate API reference, just run ``make html``. It runs
 ``mkapiref.py`` and then run Sphinx to build the entire document.
 The ``mkapiref.py`` reads C source code and searches the comment block
 starts with ``/**``. In other words, it only processes the comment
 block starting ``/**``. The comment block must end with ``*/``. The
 ``mkapiref.py`` requires that which type of the object this comment
 block refers to.  To specify the type of the object, the next line
 must contain the so-called action keyword.  Currently, the following
 action keywords are supported: ``@function``, ``@functypedef``,
 ``@enum``, ``@struct`` and ``@union``. The following sections
 describes each action keyword.
@function
 #########
 ``@function`` is used to refer to the function.  The comment block is
 used for the document for the function.  After the script sees the end
 of the comment block, it consumes the lines as the function
 declaration until the line which ends with ``;`` is encountered.
 In Sphinx doc, usually the function argument is formatted like
 ``*this*``.  But in C, ``*`` is used for dereferencing a pointer and
 we must escape ``*`` with a back slash. To avoid this, we format the
 argument like ``|this|``. The ``mkapiref.py`` translates it with
 ``*this*``, as escaping ``*`` inside ``|`` and ``|`` as necessary.
 Note that this shadows the substitution feature of Sphinx.
 The example follows::
    /**
     * @function
     *
     * Submits PING frame to the |session|.
     */
    int nghttp2_submit_ping(nghttp2_session *session);
@functypedef
 ############
 ``@functypedef`` is used to refer to the typedef of the function
 pointer. The formatting rule is pretty much the same with
 ``@function``, but this outputs ``type`` domain, rather than
 ``function`` domain.
 The example follows::
    /**
     * @functypedef
     *
     * Callback function invoked when |session| wants to send data to
     * remote peer.
     */
    typedef ssize_t (*nghttp2_send_callback)
    (nghttp2_session *session,
     const uint8_t *data, size_t length, int flags, void *user_data);
@enum
 #####
 ``@enum`` is used to refer to the enum.  Currently, only enum typedefs
 are supported.  The comment block is used for the document for the
 enum type itself. To document each values, put comment block starting
 with the line ``/**`` and ending with the ``*/`` just before the enum
 value.  When the line starts with ``}`` is encountered, the
 ``mkapiref.py`` extracts strings next to ``}`` as the name of enum.
 At the time of this writing, Sphinx does not support enum type. So we
 use ``type`` domain for enum it self and ``macro`` domain for each
 value. To refer to the enum value, use ``:enum:`` pseudo role. The
 ``mkapiref.py`` replaces it with ``:macro:``. By doing this, when
 Sphinx will support enum officially, we can replace ``:enum:`` with
 the official role easily.
 The example follows::
    /**
     * @enum
     * Error codes used in the nghttp2 library.
     */
    typedef enum {
      /**
       * Invalid argument passed.
       */
      NGHTTP2_ERR_INVALID_ARGUMENT = -501,
      /**
       * Zlib error.
       */
      NGHTTP2_ERR_ZLIB = -502,
    } nghttp2_error;
@struct
 #######
 ``@struct`` is used to refer to the struct. Currently, only struct
 typedefs are supported. The comment block is used for the document for
 the struct type itself.To document each member, put comment block
 starting with the line ``/**`` and ending with the ``*/`` just before
 the member.  When the line starts with ``}`` is encountered, the
 ``mkapiref.py`` extracts strings next to ``}`` as the name of struct.
 The block-less typedef is also supported. In this case, typedef
 declaration must be all in one line and the ``mkapiref.py`` uses last
 word as the name of struct.
 Some examples follow::
    /**
     * @struct
     * The control frame header.
     */
    typedef struct {
      /**
       * SPDY protocol version.
       */
      uint16_t version;
      /**
       * The type of this control frame.
       */
      uint16_t type;
      /**
       * The control frame flags.
       */
      uint8_t flags;
      /**
       * The length field of this control frame.
       */
      int32_t length;
    } nghttp2_ctrl_hd;
    /**
     * @struct
     *
     * The primary structure to hold the resources needed for a SPDY
     * session. The details of this structure is hidden from the public
     * API.
     */
    typedef struct nghttp2_session nghttp2_session;
@union
 ######
 ``@union`` is used to refer to the union. Currently, ``@union`` is an
 alias of ``@struct``.
