      The <application>FOP</application> (Formatting Objects Processor)
      package contains a print formatter driven by XSL formatting objects
      (XSL-FO). It is a <application>Java</application> application that reads
      a formatting object tree and renders the resulting pages to a specified
      output. Output formats currently supported include PDF, PCL, PostScript,
      SVG, XML (area tree representation), print, AWT, MIF and ASCII text. The
      primary output target is PDF.

      <para>
        The <command>javadoc</command> command coming with OpenJDK 8 has
        become much stricter than before regarding the conformance of the
        Javadoc comments in source code to HTML. The FOP documentation does
        not meet those standard, so the conformance checks have to be
        disabled. This can be done with the following command:
      </para>

<screen><userinput>sed -i '\@&lt;/javad@i\

&lt;arg value="--allow-script-in-comments"/&gt;' build.xml</userinput></screen>

      <para>
        Using <application>fop</application> to process some large FO's
        (including the FO derived from the BLFS XML sources), can lead to
        memory errors. Unless you add a parameter to the
        <command>java</command> command used in the <command>fop</command>
        script you may receive messages similar to the one shown below:
      </para>

      <para>
        <computeroutput>
          Exception in thread "main" java.lang.OutOfMemoryError: Java heap
          space
        </computeroutput>
      </para>

      <para>
        To avoid errors like this, you need to pass an extra parameter to
        the <command>java</command> command used in the <command>fop</command>
        script. This can be accomplished by creating a
        <filename>~/.foprc</filename> (which is sourced by the
        <command>fop</command> script) and adding the parameter to the
        <envar>FOP_OPTS</envar> environment variable.
      </para>

      <para>
        The <command>fop</command> script looks for a
        <envar>FOP_HOME</envar> environment variable to locate the
        <application>fop</application> class libraries. You can create this
        variable using the <filename>~/.foprc</filename> file as well. Create
        a <filename>~/.foprc</filename> file using the following commands:
      </para>

<screen><userinput>cat &gt; ~/.foprc &lt;&lt; "EOF"
<literal>FOP_OPTS="-Xmx<replaceable>&lt;RAM_Installed&gt;</replaceable>m"
FOP_HOME="/opt/fop"</literal>
EOF</userinput></screen>

      <para>
        Replace <replaceable>&lt;RAM_Installed&gt;</replaceable> with a
        number representing the amount of RAM installed in your computer (in
        megabytes). An example would be
        <userinput>FOP_OPTS="-Xmx768m"</userinput>.
        <!--  the URL is broken

        -->
      </para>

      <para>
        To include the <command>fop</command> script in your path,
        update your personal or system-wide profile with the following:
      </para>

<screen><literal>PATH=$PATH:/opt/fop</literal></screen>

      <note>
        <para>
          Running <command>fop</command> can be somewhat verbose.
          The default logging level can be changed from INFO to any of
          FINEST, FINER, FINE, CONFIG, INFO, WARNING, SEVERE, ALL, or OFF.
          To do this, edit
          <filename>$JAVA_HOME/jre/lib/logging.properties</filename> and change
          the entries for <option>.level</option> and
          <option>java.util.logging.ConsoleHandler.level</option> to
