<chapter id="tools">
  <title>Tools</title>
  
  <para>The FDP uses a number of different software tools to help
    manage the FreeBSD documentation, convert it to different output
    formats, and so on.  You will need to use these tools yourself if
    you are to work with the FreeBSD documentation.</para>                    

  <para>All these tools are available as FreeBSD Ports and Packages,
    greatly simplifying the work you have to do to install
    them.</para>                                                              
  
  <para>You will need to install these tools before you work through
    any of the examples in later chapters.  The actual usage of these
    tools is covered in later chapters.</para>     

  <tip>
    <title>Use <filename role="package">textproc/docproj</filename> if possible</title>

    <para>You can save yourself a lot of time if you install the
      <filename role="package">textproc/docproj</filename> port.  This is a
      <emphasis>meta-port</emphasis> which does not contain any software
      itself.  Instead, it depends on various other ports being installed
      correctly.  Installing this port <emphasis>should</emphasis>
      automatically download and install all of the packages listed in this
      chapter that you need.</para>

    <para>One of the packages that you might need is the JadeTeX macro set.
      In turn, this macro set requires that TeX is installed.  TeX is a large
      package, and you only need it if you want to produce Postscript or PDF
      output.</para>

    <para>To save yourself time and space you must specify whether or not you
      want JadeTeX (and therefore TeX) installed when you install this port.
      Either do;

      <screen>&prompt.root; <userinput>make JADETEX=yes install</userinput></screen>

      or

      <screen>&prompt.root; <userinput>make JADETEX=no install</userinput></screen>

      as necessary.</para>

    <title>Optional tools</title>

    <para>You do not need to have any of the following installed.  However,
      you may find it easier to work with the documentation if you do, and
      they may give you more flexibility in the output formats that can be

	  <listitem>
	    <para><application>Jade</application> and

	      documents to DVI, Postscript, and PDF formats.  The
	      <application>JadeTeX</application> macros are needed in order to
	      do this.</para>

	    <para>If you do not intend to convert your documentation to one of
	      these formats (i.e., HTML, plain text, and RTF are sufficient)
	      then you do not need to install
	      <application>JadeTeX</application> and
	      <application>teTeX</application>.  This can be a significant
	      space and time saver, as <application>teTeX</application> is
	      over 30MB in size.</para>

	    <important>
	      <para>If you decide to install
		<application>JadeTeX</application> and
		<application>teTeX</application> then you will need to
		configure <application>teTeX</application> after

	    <para>Both these editors include a special mode for editing
	      documents marked up according to an SGML DTD.  This mode
	      includes commands to reduce the amount of typing you need, and
	      help reduce the possibility of errors.</para>

	    <para>You do not need to use them; any text editor can be used to
	      edit marked up documents.  You may find they make you more
	      efficient.</para>
