  <emphasis>Windows</emphasis> binaries may be found at
  <ulink url="&url.php.snapshots;">&url.php.snapshots;</ulink>.
  To install, download php_ssh2.dll to the folder specified
  by your php.ini file's <literal>extension_dir</literal> directive.
  Enable it by adding <literal>extension=php_ssh2.dll</literal>
  to your php.ini and restarting your webserver.

  <emphasis>Linux, BSD, and other *nix variants</emphasis>
  can be compiled using the following steps:

 <itemizedlist>
  <listitem>
   <simpara>
    Download and install <ulink url="&url.openssl;">OpenSSL</ulink>.
    If you install OpenSSL via your distribution's packaging system
    be sure to install the development libraries as well.
    This will typically be a package named <literal>openssl-dev</literal>,
    <literal>openssl_devel</literal>, or some variation thereof.
   </simpara>
  </listitem>

  <listitem>
   <simpara>
    Download and install <ulink url="&url.libssh2;">libssh2</ulink>.
    Typically this means executing the following command from
    the libssh2 source tree. <literal>./configure && make all install</literal>.
   </simpara>
  </listitem>

  <listitem>
   <simpara>
    Run the pear installer for PECL/ssh2: <literal>pear install ssh2</literal>
   </simpara>
  </listitem>

  <listitem>
   <simpara>
    Copy <literal>ssh2.so</literal> from the directory indicated by the
    build process to the location specified in your php.ini file under
    <literal>extension_dir</literal>.
   </simpara>
  </listitem>

  <listitem>
   <simpara>
    Add <literal>extension=ssh2.so</literal> to your php.ini
   </simpara>
  </listitem>

  <listitem>
   <simpara>
    Restart your webserver to reload your php.ini settings.
   </simpara>
  </listitem>

 </itemizedlist>

 <note>
  <title>Development Versions</title>
  <simpara>
   There are currently no <literal>stable</literal> versions of PECL/ssh2,
   to force installation of the <literal>beta</literal> version of PECL/ssh2
   execute: <literal>pear install ssh2-</literal><emphasis>beta</emphasis>
  </simpara>
 </note>

 <tip>
  <title>Compiling PECL/ssh2 without using the PEAR command</title>
  <simpara>
   Rather than using <literal>pear install ssh2</literal> to automatically
   download and install PECL/ssh2, you may download the tarball from
   <ulink url="&url.pecl.package;ssh2">PECL</ulink>.
   From the root of the unpacked tarball, run:
   <literal>phpize && ./configure && make</literal> to generate
   <literal>ssh2.so</literal>.
   Once built, continue the installation from step 4 above.
  </simpara>

 <note>
  <simpara>
   You will need version 0.4 or greater of the libssh2 library
   (possibly higher, see release notes).
