-# SYNOPSIS
-#
-#   AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
-#
-# DESCRIPTION
-#
-#   Check whether the given FLAG works with the current language's compiler
-#   or gives an error.  (Warnings, however, are ignored)
-#
-#   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
-#   success/failure.
-#
-#   If EXTRA-FLAGS is defined, it is added to the current language's default
-#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
-#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
-#   force the compiler to issue an error when a bad flag is given.
-#
-#   INPUT gives an alternative input source to AC_LINK_IFELSE.
-#
-#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
-#   macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

-<h3><a name="DESCRIPTION">DESCRIPTION</a></h3>
-
-<p>This extension provides a generic binding to <a
-href="http://www.openssl.org/">OpenSSL</a>, utilizing the
-<strong>Tcl_StackChannel</strong>
-API for Tcl 8.4 and higher. The sockets behave exactly the same
-as channels created using Tcl's built-in <strong>socket</strong>
-command with additional options for controlling the SSL session.
-</p>
-
-<h3><a name="COMMANDS">COMMANDS</a></h3>
-
-<p>Typically one would use the <strong>tls::socket </strong>command
-which provides compatibility with the native Tcl <strong>socket</strong>
-command. In such cases <strong>tls::import</strong> should not be
-used directly.</p>
-
-<dl>
-    <dt><a name="tls::init"><b>tls::init </b><i>?options?</i></a></dt>
-    <dd>This routine sets the default options used by <strong>tls::socket</strong>
-        and is <em>optional</em>. If you call <strong>tls::import</strong>
-        directly this routine has no effect. Any of the options
-        that <strong>tls::socket</strong> accepts can be set
-        using this command, though you should limit your options
-        to only TLS related ones.</dd>
-    <dt>&nbsp;</dt>
-    <dt><a name="tls::socket"><b>tls::socket </b><em>?options?
-        host port</em></a></dt>
-    <dt><b>tls::socket</b><em> ?-server command? ?options? port</em></dt>
-    <dd>This is a helper function that utilizes the underlying
-        commands (<strong>tls::import</strong>). It behaves
-        exactly the same as the native Tcl <strong>socket</strong>
-        command except that the options can include any of the
-        applicable <a href="#tls::import"><strong>tls:import</strong></a>
-        options with one additional option:
-<blockquote>

-</blockquote>
-    <dt>&nbsp;</dt>
-    <dt><a name="tls::handshake"><strong>tls::handshake</strong> <em>channel</em></a></dt>
-    <dd>Forces handshake to take place, and returns 0 if
-        handshake is still in progress (non-blocking), or 1 if
-        the handshake was successful. If the handshake failed
-        this routine will throw an error.</dd>
-    <dt>&nbsp;</dt>
-    <dt><a name="tls::status"><strong>tls::status</strong>
-    <em>?-local? channel</em></a></dt>
-    <dd>Returns the current security status of an SSL channel. The
-        result is a list of key-value pairs describing the
-        connected peer. If the result is an empty list then the
-        SSL handshake has not yet completed.
-        If <em>-local</em> is given, then the certificate information
-        is the one used locally.</dd>

-Reference implementations of these callbacks are provided in the

-<em>sample</em> implementations only.  In a more realistic deployment
-you would specify your own callback scripts on each TLS channel
-using the <em>-command</em> and <em>-password</em> options.
-</p>
-
-<p>
-The default behavior when the <em>-command</em> option is not specified is for
-TLS to process the associated library callbacks internally.
-The default behavior when the <em>-password</em> option is not specified is for
-TLS to process the associated library callbacks by attempting to call
-<strong>tls::password</strong>.
-The difference between these two behaviors is a consequence of maintaining
-compatibility with earlier implementations.
-</p>
-
-<p>
-The <strong>tls::debug</strong> variable provides some additional
-control over these reference callbacks.  Its value is zero by default.
-Higher values produce more diagnostic output, and will also force the
-verify method in <strong>tls::callback</strong> to accept the
-certificate, even when it is invalid.

-<h3><a name="SPECIAL CONSIDERATIONS">SPECIAL CONSIDERATIONS</a></h3>
-
-<p>The capabilities of this package can vary enormously based
-upon how your OpenSSL library was configured and built. At the
-most macro-level OpenSSL supports a &quot;no patents&quot; build,
-which disables RSA, IDEA, RC(2,4,5) and SSL2 - if your OpenSSL is
-configured this way then you will need to build TLS with the
--DNO_PATENTS option - and the resultant module will function
-correctly and also support ADH certificate-less encryption,
-however you will be unable to utilize this to speak to normal Web
-Servers, which typically require RSA support. Please see <a
-href="http://www.openssl.org/">http://www.openssl.org/</a> for
-more information on the whole issue of patents and US export
-restrictions. </p>

+
+<p>This extension provides a generic binding to <a
+href="http://www.openssl.org/">OpenSSL</a>, utilizing the
+<strong>Tcl_StackChannel</strong>
+API for Tcl 8.4 and higher. The sockets behave exactly the same
+as channels created using Tcl's built-in <strong>socket</strong>
+command with additional options for controlling the SSL session.
+</p>
+
+<h3><a name="COMMANDS">COMMANDS</a></h3>
+
+<p>Typically one would use the <strong>tls::socket </strong>command
+which provides compatibility with the native Tcl <strong>socket</strong>
+command. In such cases <strong>tls::import</strong> should not be
+used directly.</p>

+
+<p>
+As indicated above, individual channels can be given their own callbacks
+to handle intermediate processing by the OpenSSL library, using the
+<em>-command</em> and <em>-password</em> options passed to either of
+<strong>tls::socket</strong> or <strong>tls::import</strong>.
+</p>
+
+<blockquote>
+<dl>
+
+    <dt><strong>-command</strong> <em>callback</em></dt>
+    <dd>
+	Invokes the specified <em>callback</em> script at
+	several points during the OpenSSL handshake.
+	Except as indicated below, values returned from the
+	callback are ignored.
+	Arguments appended to the script upon callback take one of the
+	following forms:
+
+	<br>
+	<br>
+
+	<dl>
+
+<!--	This form of callback is disabled.
+
+	<dt>
+	  <strong>error</strong> <em>channel message</em>
+	</dt>
+	<dd>
+	  The <em>message</em> argument contains an error message generated
+	  by the OpenSSL function
+	  <code>ERR_reason_error_string()</code>.
+	</dd>
+
+	<br>
+-->
+
+	<dt>
+	  <strong>info</strong> <em>channel major minor message</em>
+	</dt>
+	<dd>
+	  This form of callback is invoked by the OpenSSL function
+	  <code>SSL_CTX_set_info_callback()</code>.
+	  <br>
+	  The <em>major</em> and <em>minor</em> arguments are used to
+	  represent the state information bitmask.
+	  <dl>
+	  <dt>Possible values for <em>major</em> are:</dt>
+	  <dd><code>handshake, alert, connect, accept</code>.</dd>
+	  <dt>Possible values for <em>minor</em> are:</dt>
+	  <dd><code>start, done, read, write, loop, exit</code>.</dd>
+	  </dl>
+	  The <em>message</em> argument is a descriptive string which may
+	  be generated either by
+	  <code>SSL_state_string_long()</code> or by
+	  <code>SSL_alert_desc_string_long()</code>,
+	  depending on context.
+	</dd>
+
+	<br>
+
+	<dt>
+	  <strong>verify</strong> <em>channel depth cert status error</em>
+	</dt>
+	<dd>
+	  This form of callback is invoked by the OpenSSL function
+	  <code>SSL_set_verify()</code>.
+	  <br>
+	  The <em>depth</em> argument is an integer representing the
+	  current depth on the certificate chain, with
+	  <code>0</code> as the subject certificate and higher values
+	  denoting progressively more indirect issuer certificates.
+	  <br>
+	  The <em>cert</em> argument is a list of key-value pairs similar
+	  to those returned by
+	  <a href="#tls::status"><strong>tls::status</strong></a>.
+	  <br>
+	  The <em>status</em> argument is an integer representing the
+	  current validity of the certificate.
+	  A value of <code>0</code> means the certificate is deemed invalid.
+	  A value of <code>1</code> means the certificate is deemed valid.
+	  <br>
+	  The <em>error</em> argument supplies the message, if any, generated
+	  by
+	  <code>X509_STORE_CTX_get_error()</code>.
+	  <br>
+	  <br>
+	  The callback may override normal validation processing by explicitly
+	  returning one of the above <em>status</em> values.
+	</dd>
+
+	</dl>
+    </dd>
+
+    <br>
+
+    <dt><strong>-password</strong> <em>callback</em></dt>
+    <dd>
+	Invokes the specified <em>callback</em> script when OpenSSL needs to
+	obtain a password.  The callback should return a string which
+	represents the password to be used.
+	No arguments are appended to the script upon callback.
+    </dd>
+</dl>
+</blockquote>
+
+<p>
+Reference implementations of these callbacks are provided in the
+distribution as <strong>tls::callback</strong> and
+<strong>tls::password</strong> respectively.  Note that these are
+<em>sample</em> implementations only.  In a more realistic deployment
+you would specify your own callback scripts on each TLS channel
+using the <em>-command</em> and <em>-password</em> options.
+</p>
+
+<p>
+The default behavior when the <em>-command</em> option is not specified is for
+TLS to process the associated library callbacks internally.
+The default behavior when the <em>-password</em> option is not specified is for
+TLS to process the associated library callbacks by attempting to call
+<strong>tls::password</strong>.
+The difference between these two behaviors is a consequence of maintaining
+compatibility with earlier implementations.
+</p>
+
+<p>
+The <strong>tls::debug</strong> variable provides some additional
+control over these reference callbacks.  Its value is zero by default.
+Higher values produce more diagnostic output, and will also force the
+verify method in <strong>tls::callback</strong> to accept the
+certificate, even when it is invalid.
+</p>
+
+<p>
+<em>
+The use of the reference callbacks <strong>tls::callback</strong> and
+<strong>tls::password</strong> is not recommended.  They may be removed
+from future releases.
+</em>
+</p>
+
+<p>
+<em>
+The use of the variable <strong>tls::debug</strong> is not recommended.
+It may be removed from future releases.
+</em>
+</p>
+
+<h3><a name="DEBUG">DEBUG</a></h3>
+
+TLS key logging can be enabled by setting the environment variable
+<b>SSLKEYLOGFILE</b> to the name of the file to log to. Then whenever TLS
+key material is generated or received it will be logged to the file.
+
+<h3><a name="HTTPS EXAMPLE">HTTPS EXAMPLE</a></h3>
+
+<p>This example uses a sample server.pem provided with the TLS release,
+courtesy of the <strong>OpenSSL</strong> project.</p>

+</code></pre>
+
+<h3><a name="SPECIAL CONSIDERATIONS">SPECIAL CONSIDERATIONS</a></h3>
+
+<p>The capabilities of this package can vary enormously based
+upon how your OpenSSL library was configured and built. At the
+most macro-level OpenSSL supports a &quot;no patents&quot; build,
+which disables RSA, IDEA, RC(2,4,5) and SSL2 - if your OpenSSL is
+configured this way then you will need to build TLS with the
+-DNO_PATENTS option - and the resultant module will function
+correctly and also support ADH certificate-less encryption,
+however you will be unable to utilize this to speak to normal Web
+Servers, which typically require RSA support. Please see <a
+href="http://www.openssl.org/">http://www.openssl.org/</a> for
+more information on the whole issue of patents and US export
+restrictions. </p>
