    <title>Installation of JS</title>

    <caution>
      <para>If you are reinstalling JS60 with the security patch listed in this
      page, save all work and exit your GNOME Session if you have one running.
      Replacing the JS60 binary will cause the GNOME Shell to crash and return
      you to your display manager or TTY. After installing the patch, 
      reinstall <xref linkend="gjs"/>. Polkit is unaffected.</para>
    </caution>

    <para>
      First, apply a security patch:
    </para>

<screen><userinput remap="pre">patch -Np1 -i ../js60-&JS60-version;-security_fix-1.patch</userinput></screen>

    <para>
      Install <application>JS</application> by running the following
      commands:
    </para>

    &shell-env;

<screen><userinput>mkdir mozjs-build &amp;&amp;

      <parameter>--with-*</parameter>: These parameters allow the build system
      to use system versions of the above libriares. These are required for
      stability.

    <para>
      <parameter>--enable-readline</parameter>: This switch enables Readline
      support in the JS shell.

    <para>
      <parameter>--disable-jemalloc</parameter>: This switch disables the
      internal memory allocator used in JS60. jemalloc causes a conflict with glibc.
