-  <section>
-    <title>General</title>
-
-    <p>This manual page describes functions that are defined
-      in the ssl module and represents the old ssl implementation
-      that coexists with the new one until it has been
-      totally phased out. </p>
-
-   <p>The old implementation can be
-      accessed by providing the option {ssl_imp, old} to the
-      ssl:connect and ssl:listen functions.</p>
-      
-    <p>The reader is advised to also read the <c>ssl(6)</c> manual page
-      describing the SSL application.
-      </p>
-    <warning>
-      <p>It is strongly advised to seed the random generator after
-        the ssl application has been started (see <c>seed/1</c>
-        below), and before any connections are established. Although
-        the port program interfacing to the ssl libraries does a
-        "random" seeding of its own in order to make everything work
-        properly, that seeding is by no means random for the world
-        since it has a constant value which is known to everyone
-        reading the source code of the port program.</p>

-    <p>The socket option <c>{backlog, integer()}</c> is for
-      <c>listen/2</c> only, and the option <c>{port, integer()}</c>
-      is for <c>connect/3/4</c> only. 
-      </p>
-    <p>The following socket options are set by default: <c>{mode, list}</c>, <c>{packet, 0}</c>, <c>{header, 0}</c>, <c>{nodelay, false}</c>, <c>{active, true}</c>, <c>{backlog, 5}</c>,
-      <c>{ip, {0,0,0,0}}</c>, and <c>{port, 0}</c>.
-      </p>
-    <p>Note that the options <c>{mode, binary}</c> and <c>binary</c>
-      are equivalent. Similarly <c>{mode, list}</c> and the absence of
-      option <c>binary</c> are equivalent. 
-      </p>
-    <p>The ssl options are for setting specific SSL parameters as follows:
-      </p>
-    <list type="bulleted">
-      <item>
-        <p><c>{verify, code()}</c> Specifies type of verification:
-          0 = do not verify peer; 1 = verify peer, 2 = verify peer,
-          fail if no peer certificate.  The default value is 0.
-          </p>
-      </item>
-      <item>
-        <p><c>{depth, depth()}</c> Specifies the maximum
-          verification depth, i.e. how far in a chain of certificates
-          the verification process can proceed before the verification
-          is considered to fail. 
-          </p>
-        <p>Peer certificate = 0, CA certificate = 1, higher level CA
-          certificate = 2, etc.  The value 2 thus means that a chain
-          can at most contain peer cert, CA cert, next CA cert, and an
-          additional CA cert.
-          </p>
-        <p>The default value is 1.
-          </p>
-      </item>
-      <item>
-        <p><c>{certfile, path()}</c> Path to a file containing the
-          user's certificate.
-          chain of PEM encoded certificates.</p>
-      </item>
-      <item>
-        <p><c>{keyfile, path()}</c> Path to file containing user's
-          private PEM encoded key.</p>
-      </item>
-      <item>
-        <p><c>{password, string()}</c> String containing the user's
-          password. Only used if the private keyfile is password protected.</p>
-      </item>
-      <item>
-        <p><c>{cacertfile, path()}</c> Path to file containing PEM encoded
-          CA certificates (trusted certificates used for verifying a peer
-          certificate).</p>
-      </item>
-      <item>
-        <p><c>{ciphers, string()}</c> String of ciphers as a colon
-          separated list of ciphers. The function <c>ciphers/0</c> can
-          be used to find all available ciphers.</p>
-      </item>
-    </list>
-    <p>The type <c>sslsocket()</c> is opaque to the user.
-      </p>
-    <p>The owner of a socket is the one that created it by a call to
-      <c>transport_accept/[1,2]</c>,  <c>connect/[3,4]</c>,
-      or <c>listen/2</c>.
-      </p>
-    <p>When a socket is in active mode (the default), data from the
-      socket is delivered to the owner of the socket in the form of
-      messages:
-      </p>
-    <list type="bulleted">
-      <item>
-        <p><c>{ssl, Socket, Data}</c></p>
-      </item>
-      <item>
-        <p><c>{ssl_closed, Socket}</c></p>
-      </item>
-      <item>
-        <p><c>{ssl_error, Socket, Reason}</c></p>
-      </item>
-    </list>
-    <p>A <c>Timeout</c> argument specifies a timeout in milliseconds. The 
-      default value for a <c>Timeout</c> argument is <c>infinity</c>.
-      </p>
-    <p>Functions listed below may return the value <c>{error, closed}</c>, which only indicates that the SSL socket is
-      considered closed for the operation in question. It is for
-      instance possible to have <c>{error, closed}</c> returned from
-      an call to <c>send/2</c>, and a subsequent call to <c>recv/3</c>
-      returning <c>{ok, Data}</c>.
-      </p>
-    <p>Hence a return value of <c>{error, closed}</c> must not be
-      interpreted as if the socket was completely closed. On the
-      contrary, in order to free all resources occupied by an SSL
-      socket, <c>close/1</c> must be called, or else the process owning
-      the socket has to terminate.
-      </p>
-    <p>For each SSL socket there is an Erlang process representing the
-      socket.  When a socket is opened, that process links to the
-      calling client process.  Implementations that want to detect
-      abnormal exits from the socket process by receiving <c>{'EXIT', Pid, Reason}</c> messages, should use the function <c>pid/1</c>
-      to retrieve the process identifier from the socket, in order to
-      be able to match exit messages properly.</p>

-          of its own in order to make everything work properly, that
-          seeding is by no means random for the world since it has a 
-          constant value which is known to everyone reading the source
