   Introduction
  </h2>
  <p>
   w3m is a pager/text-based WWW browser. You can browse local
   documents and/or documents on the WWW using a terminal emulator.
  </p>
  <hr>
  <h2 id="Options">
   Options
  </h2>
  <p>
   Command line usage is
  </p>
<pre>
    w3m [options] [file|URL]
</pre>
  <p>
   If you specify filenames/URLs on the command line, these documents
   are displayed. If you specify nothing, w3m will read a document
   from standard input and display it. If it doesn't find a document
   there either then normally w3m will terminate.
  </p>
  <p>
   Options include:
  </p>
  <dl>
   <dt>
    +<i>number</i>
   </dt>
   <dd>
    <p>
     Move to the specified line-number.
    </p>
   </dd>
  <dt>
    -t <i>width</i>
    <!--mh 2016-03-29 -t <i>num</i>-->
   </dt>
   <dd>
    <p>
      Specify tab width. Default is 8.
      <!--mh 2016-03-29 set tab width to num columns. No effect on stdout-->
    </p>
   </dd>
   <dt>
    -r
   </dt>
   <dd>
    <p>
     When displaying text/plain documents, prohibit emphasis using
     backspace. If you don't specify this option, <q>A^H_</q> is
     interpreted as an underlined <q>A</q> and <q>A^HA</q> as a bold
     <q>A</q>.
<!-- mh 2016-03-29 
use caret notation to display special escape characters (such as ANSI escapes or nroff-style backspaces for bold  and  underlined characters) instead of processing them
-->
    </p>
   </dd>
   <dt>
    -l <i>number</i>
   </dt>
   <dd>
    <p>
     Specify the number of lines that should be cached while reading a
     text/plain document from standard input. Default is 10,000.
    </p>
   </dd>
   <dt>
    -O <i>charset</i>
   </dt>
   <dd>
    <p>
     Specify display/output charset.
<!-- mh 2016-03-29
user defined character encoding of output data
-->
    </p>
   </dd>
   <dt>
    -I <i>charset</i>
   </dt>
   <dd>
    <p>
     Specify document charset.
<!-- mh 2016-03-29
user defined character encoding of input data
-->
    </p>
   </dd>
   <dt>
    -T <i>type</i>
   </dt>
   <dd>
    <p>
     Specify document type. Without this option, document type is
     determined from the extension of a file. If the determination
     fails, the document is regarded as text/plain. For example:
    </p>
    <p>
     Read HTML document from standard input and display it
    </p>
<pre>
   cat example.html | w3m -T text/html
</pre>
   <p>
    Display HTML source
   </p>
<pre>
   w3m -T text/plain example.html
</pre>
   </dd>
   <dt>
    -m
   </dt>
   <dd>
    <p>
     Display document using <q>Internet message mode</q>. With this
     option, w3m determines document type from header information.
     This is useful when reading e-mail or Usenet news posts.
<!-- mh 2016-03-29
Render the body of Usenet messages according to the header <q>Content-type</q>

   If w3m is compiled with mouse support and you are invoking w3m
   either from a console with GPM or from an X terminal emulator, you
   can use the mouse for navigation (in the case of rxvt, you need to
   set the TERM environment variable to <q>xterm</q> or <q>kterm</q>).

  <h2 id="Key:custom">
   Key customization
  </h2>
  <p>
   You can customize the key bindings (except the line-editing keymap)
   in a ~/.w3m/keymap file. For example,
  </p>
<pre>

   keymap C-o NEXT_PAGE

</pre>
  <p>
   binds the <q>NEXT_PAGE</q> function (normally bound to SPC and C-v)
   to control-o. See <a href="README.func">README.func</a> for a
   list of available functions. Original and Lynx-like keymap
   definitions are provided (<a href="keymap.default">keymap.default</a>
   and <a href="keymap.lynx">keymap.lynx</a>) as examples.
  </p>
  <hr>
  <h2 id="LocalCGI">
   Local CGI
  </h2>
  <p>
   You can run CGI scripts using w3m, without any HTTP server.
   This means that w3m behaves like an HTTP server and runs the CGI
   script, then reads the output of the script and displays it. For
   example, the bookmark registration system and default directory
   browser are realized as local CGI scripts. Moreover, such scripts
   allow w3m to be used as a form interface to acquire all kinds of
   data.
  </p>
  <p>
   For security reason, CGI scripts invoked by w3m must be in one of
   the following directories:
  </p>
  <ul>
   <li>
    The directory where w3m-related files are stored (typically
    /usr/local/lib/w3m). This directory can be referenced as $LIB.
   </li>
   <li>
    The /cgi-bin/ directory. You can map /cgi-bin/ to any directory you
    like in the option setting panel (the <q>Directory corresponds to
    /cgi-bin</q> field). You can specify multiple paths separated by
    <q>:</q>, like /usr/local/cgi-bin:/home/aito/cgi-bin. To use a
    /cgi-bin/ directory, you must use a file:/cgi-bin URL as follows:
<pre>
 w3m -o cgi_bin=/path/to/cgi-bin file:/cgi-bin/script.cgi
</pre>
    It is not recommended to include the current directory to this path.
   </li>
  </ul>
  <p>
   The CGI script can use the special header <q>w3m-control:</q> to
   control w3m. This field can take any function (see
   <a href="README.func">README.func</a>), and the specified function
   is invoked after the document is displayed. For example, the CGI
   output
  </p>
<pre>

Content-Type: text/plain
W3m-control: BACK

</pre>
  <p>
   will display a blank page and delete that buffer immediately.
   This is useful when you don't want to display any page after
   the script is invoked. The next example
  </p>
<pre>

Content-Type: text/plain
W3m-control: DELETE_PREVBUF

contents.....
</pre>
  <p>
   will override the current buffer.
  </p>
  <p>
   Each w3m-control: header can contain only one function, but you can
   include more than one w3m-control: line in the HTTP header.
   In addition, you can specify an argument to the GOTO function:
  </p>
<pre>

Content-Type: text/plain
W3m-control: GOTO http://www.example.org/

</pre>
   <p>
    This example works exactly the same way as the Location header:
   </p>
<pre>

Content-Type: text/plain
Location: http://www.example.org/

</pre>
  <p>
   Note that this header has no effect when the CGI script is invoked
   through an HTTP server.

  <h2 id="Introduction">
   Introduction
  </h2>
  <p>
   w3m is a pager/text-based WWW browser. You can browse local
   documents and/or documents on the WWW using a terminal emulator.
  </p>
  <hr>
  <h2 id="Options">
   Options
  </h2>
  <p>
   Command line usage is
  </p>
<pre>
    w3m [options] [file|URL]
</pre>
  <p>
   If you specify filenames/URLs on the command line, these documents
   are displayed. If you specify nothing, w3m will read a document
   from standard input and display it. If it doesn't find a document
   there either then normally w3m will terminate.
  </p>
  <p>
   Options include:
  </p>
  <dl>
   <dt>
    +<i>number</i>
   </dt>
   <dd>
    <p>
     Move to the specified line-number.
    </p>
   </dd>
  <dt>
    -t <i>width</i>
    <!--mh 2016-03-29 -t <i>num</i>-->
   </dt>
   <dd>
    <p>
      Specify tab width. Default is 8.
      <!--mh 2016-03-29 set tab width to num columns. No effect on stdout-->
    </p>
   </dd>
   <dt>
    -r
   </dt>
   <dd>
    <p>
     When displaying text/plain documents, prohibit emphasis using
     backspace. If you don't specify this option, <q>A^H_</q> is
     interpreted as an underlined <q>A</q> and <q>A^HA</q> as a bold
     <q>A</q>.
<!-- mh 2016-03-29 
use caret notation to display special escape characters (such as ANSI escapes or nroff-style backspaces for bold  and  underlined characters) instead of processing them
-->
    </p>
   </dd>
   <dt>
    -l <i>number</i>
   </dt>
   <dd>
    <p>
     Specify the number of lines that should be cached while reading a
     text/plain document from standard input. Default is 10,000.
    </p>
   </dd>
   <dt>
    -O <i>charset</i>
   </dt>
   <dd>
    <p>
     Specify display/output charset.
<!-- mh 2016-03-29

-->
    </p>
   </dd>
   <dt>
    -I <i>charset</i>
   </dt>
   <dd>
    <p>
     Specify document charset.
<!-- mh 2016-03-29

-->
    </p>
   </dd>
   <dt>
    -T <i>type</i>
   </dt>
   <dd>
    <p>
     Specify document type. Without this option, document type is
     determined from the extension of a file. If the determination
     fails, the document is regarded as text/plain. For example:
    </p>
    <p>
     Read HTML document from standard input and display it
    </p>
<pre>
   cat example.html | w3m -T text/html
</pre>
   <p>
    Display HTML source
   </p>
<pre>
   w3m -T text/plain example.html
</pre>
   </dd>
   <dt>
    -m
   </dt>
   <dd>
    <p>
     Display document using <q>Internet message mode</q>. With this
     option, w3m determines document type from header information.
     This is useful when reading e-mail or Usenet news posts.
<!-- mh 2016-03-29

   If w3m is compiled with mouse support and you are invoking w3m

  <h2 id="Key:custom">
   Key customization
  </h2>
  <p>
   You can customize the key bindings (except the line-editing keymap)
   in a ~/.w3m/keymap file. For example,
  </p>
<pre>

   keymap C-o NEXT_PAGE

</pre>
  <p>
   binds the <q>NEXT_PAGE</q> function (normally bound to SPC and C-v)
   to control-o. See <a href="README.func">README.func</a> for a
   list of available functions. Original and Lynx-like keymap
   definitions are provided (<a href="keymap.default">keymap.default</a>
   and <a href="keymap.lynx">keymap.lynx</a>) as examples.
  </p>
  <hr>
  <h2 id="LocalCGI">
   Local CGI
  </h2>
  <p>
   You can run CGI scripts using w3m, without any HTTP server.
   This means that w3m behaves like an HTTP server and runs the CGI
   script, then reads the output of the script and displays it. For
   example, the bookmark registration system and default directory
   browser are realized as local CGI scripts. Moreover, such scripts
   allow w3m to be used as a form interface to acquire all kinds of
   data.
  </p>
  <p>
   For security reason, CGI scripts invoked by w3m must be in one of
   the following directories:
  </p>
  <ul>
   <li>
    The directory where w3m-related files are stored (typically
    /usr/local/lib/w3m). This directory can be referenced as $LIB.
   </li>
   <li>
    The /cgi-bin/ directory. You can map /cgi-bin/ to any directory you
    like in the option setting panel (the <q>Directory corresponds to
    /cgi-bin</q> field). You can specify multiple paths separated by
    <q>:</q>, like /usr/local/cgi-bin:/home/aito/cgi-bin. To use a
    /cgi-bin/ directory, you must use a file:/cgi-bin URL as follows:
<pre>
 w3m -o cgi_bin=/path/to/cgi-bin file:/cgi-bin/script.cgi
</pre>
    It is not recommended to include the current directory to this path.
   </li>
  </ul>
  <p>
   The CGI script can use the special header <q>w3m-control:</q> to
   control w3m. This field can take any function (see
   <a href="README.func">README.func</a>), and the specified function
   is invoked after the document is displayed. For example, the CGI
   output
  </p>
<pre>

Content-Type: text/plain
W3m-control: BACK

</pre>
  <p>
   will display a blank page and delete that buffer immediately.
   This is useful when you don't want to display any page after
   the script is invoked. The next example
  </p>
<pre>

Content-Type: text/plain
W3m-control: DELETE_PREVBUF

contents.....
</pre>
  <p>
   will override the current buffer.
  </p>
  <p>
   Each w3m-control: header can contain only one function, but you can
   include more than one w3m-control: line in the HTTP header.
   In addition, you can specify an argument to the GOTO function:
  </p>
<pre>

Content-Type: text/plain
W3m-control: GOTO http://www.example.org/

</pre>
   <p>
    This example works exactly the same way as the Location header:
   </p>
<pre>

Content-Type: text/plain
Location: http://www.example.org/

</pre>
  <p>
   Note that this header has no effect when the CGI script is invoked
   through an HTTP server.
