      <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>. For more information about
      memory issues running <application>FOP</application>, see
      <ulink url="http://xml.apache.org/fop/running.html#memory"/>.</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>
