-      <title>What to Edit</title>
-      <para>
-        There are two different ways of editing of Bugzilla's templates,
-        and which you use depends mainly on how you upgrade Bugzilla. The
-        template directory structure is that there's a top level directory,
-        <filename>template</filename>, which contains a directory for
-        each installed localization. The default English templates are
-        therefore in <filename>en</filename>. Underneath that, there
-        is the <filename>default</filename> directory and optionally the 
-        <filename>custom</filename> directory. The <filename>default</filename>
-        directory contains all the templates shipped with Bugzilla, whereas
-        the <filename>custom</filename> directory does not exist at first and
-        must be created if you want to use it.
-      </para>
-
-      <para>
-        The first method of making customizations is to directly edit the
-        templates in <filename>template/en/default</filename>. This is
-        probably the best method for small changes if you are going to use
-        the CVS method of upgrading, because if you then execute a
-        <command>cvs update</command>, any template fixes will get
-        automagically merged into your modified versions.
-      </para>
-
-      <para>
-        If you use this method, your installation will break if CVS conflicts
-        occur.
-      </para>
-
-      <para>
-        The other method is to copy the templates into a mirrored directory
-        structure under <filename>template/en/custom</filename>.  The templates
-        in this directory automatically override those in default.  
-        This is the technique you
-        need to use if you use the overwriting method of upgrade, because
-        otherwise your changes will be lost.  This method is also better if
-        you are using the CVS method of upgrading and are going to make major
-        changes, because it is guaranteed that the contents of this directory
-        will not be touched during an upgrade, and you can then decide whether
-        to continue using your own templates, or make the effort to merge your
-        changes into the new versions by hand.
-      </para>
-
-      <para>
-        If you use this method, your installation may break if incompatible
-        changes are made to the template interface.  If such changes are made
-        they will be documented in the release notes, provided you are using a
-        stable release of Bugzilla.  If you use using unstable code, you will
-        need to deal with this one yourself, although if possible the changes
-        will be mentioned before they occur in the deprecations section of the
-        previous stable release's release notes.
-      </para>
-
-      <note>
-        <para>
-          Don't directly edit the compiled templates in 
-          <filename class="directory">data/template/*</filename> - your
-          changes will be lost when Template Toolkit recompiles them.
-        </para>

-        <para>It is recommended that you run <command>./checksetup.pl</command>

-      <title>How To Edit Templates</title>
-      
-     <para>
-        The syntax of the Template Toolkit language is beyond the scope of
-        this guide. It's reasonably easy to pick up by looking at the current 
-        templates; or, you can read the manual, available on the
-        <ulink url="http://www.template-toolkit.org">Template Toolkit home
-        page</ulink>. However, you should particularly remember (for security
-        reasons) to always HTML filter things which come from the database or
-        user input, to prevent cross-site scripting attacks.
-      </para>
-      
-      <para>
-        However, one thing you should take particular care about is the need
-        to properly HTML filter data that has been passed into the template.
-        This means that if the data can possibly contain special HTML characters
-        such as &lt;, and the data was not intended to be HTML, they need to be
-        converted to entity form, ie &amp;lt;.  You use the 'html' filter in the
-        Template Toolkit to do this.  If you fail to do this, you may open up
-        your installation to cross-site scripting attacks.
-      </para>
-
-      <para>
-        Also note that Bugzilla adds a few filters of its own, that are not
-        in standard Template Toolkit.  In particular, the 'url_quote' filter
-        can convert characters that are illegal or have special meaning in URLs,
-        such as &amp;, to the encoded form, ie %26.  This actually encodes most
-        characters (but not the common ones such as letters and numbers and so
-        on), including the HTML-special characters, so there's never a need to
-        HTML filter afterwards.
-      </para>
- 
-      <para>
-        Editing templates is a good way of doing a "poor man's custom fields".
-        For example, if you don't use the Status Whiteboard, but want to have
-        a free-form text entry box for "Build Identifier", then you can just
-        edit the templates to change the field labels. It's still be called
-        status_whiteboard internally, but your users don't need to know that.
-      </para>
-      
-      <note>
-        <para>
-          If you are making template changes that you intend on submitting back
-          for inclusion in standard Bugzilla, you should read the relevant
-          sections of the 
-          <ulink url="http://www.bugzilla.org/developerguide.html">Developers'
-          Guide</ulink>.

-      <title>Template Formats</title>
-      
-      <para>
-        Some CGIs have the ability to use more than one template. For
-        example, buglist.cgi can output bug lists as RDF or two
-        different forms of HTML (complex and simple). (Try this out
-        by appending <filename>&amp;format=simple</filename> to a buglist.cgi
-        URL on your Bugzilla installation.) This
-        mechanism, called template 'formats', is extensible.
-      </para>
-      
-      <para>
-        To see if a CGI supports multiple output formats, grep the
-        CGI for "ValidateOutputFormat". If it's not present, adding
-        multiple format support isn't too hard - see how it's done in
-        other CGIs.
-      </para>
-      
-      <para>
-        To make a new format template for a CGI which supports this, 
-        open a current template for
-        that CGI and take note of the INTERFACE comment (if present.) This 
-        comment defines what variables are passed into this template. If 
-        there isn't one, I'm afraid you'll have to read the template and
-        the code to find out what information you get. 
-      </para>     
-  
-      <para>
-        Write your template in whatever markup or text style is appropriate.
-      </para>
-      
-      <para>
-        You now need to decide what content type you want your template
-        served as. Open up the <filename>localconfig</filename> file and find the 
-        <filename>$contenttypes</filename>
-        variable. If your content type is not there, add it. Remember
-        the three- or four-letter tag assigned to you content type. 
-        This tag will be part of the template filename.
-      </para>
-      
-      <para>
-        Save the template as <filename>&lt;stubname&gt;-&lt;formatname&gt;.&lt;contenttypetag&gt;.tmpl</filename>. 
-        Try out the template by calling the CGI as 
-        <filename>&lt;cginame&gt;.cgi?format=&lt;formatname&gt;</filename> .

-      </para>
-      
-      <para>
-        <command>index.html.tmpl</command>:
-        This is the Bugzilla front page.
-      </para>      
-
-      <para>
-        <command>global/header.html.tmpl</command>:
-        This defines the header that goes on all Bugzilla pages.
-        The header includes the banner, which is what appears to users
-        and is probably what you want to edit instead.  However the
-        header also includes the HTML HEAD section, so you could for
-        example add a stylesheet or META tag by editing the header.
-      </para>
-
-      <para>
-        <command>global/banner.html.tmpl</command>:
-        This contains the "banner", the part of the header that appears
-        at the top of all Bugzilla pages.  The default banner is reasonably
-        barren, so you'll probably want to customize this to give your
-        installation a distinctive look and feel.  It is recommended you
-        preserve the Bugzilla version number in some form so the version 
-        you are running can be determined, and users know what docs to read.
-      </para>
-
-      <para>
-        <command>global/footer.html.tmpl</command>:
-        This defines the footer that goes on all Bugzilla pages.  Editing
-        this is another way to quickly get a distinctive look and feel for
-        your Bugzilla installation.
-      </para>
-
-      <para>
-        <command>bug/create/user-message.html.tmpl</command>:
-        This is a message that appears near the top of the bug reporting page.
-        By modifying this, you can tell your users how they should report
-        bugs.
-      </para>
-
-      <para>
-        <command>bug/process/midair.html.tmpl</command>:
-        This is the page used if two people submit simultaneous changes to the
-        same bug.  The second person to submit their changes will get this page
-        to tell them what the first person did, and ask if they wish to
-        overwrite those changes or go back and revisit the bug.  The default
-        title and header on this page read "Mid-air collision detected!"  If
-        you work in the aviation industry, or other environment where this
-        might be found offensive (yes, we have true stories of this happening)
-        you'll want to change this to something more appropriate for your
-        environment.
-      </para>
-        
-      <para>
-        <command>bug/create/create.html.tmpl</command> and
-        <command>bug/create/comment.txt.tmpl</command>:
-        You may wish to get bug submitters to give certain bits of structured
-        information, each in a separate input widget, for which there is not a
-        field in the database. The bug entry system has been designed in an
-        extensible fashion to enable you to define arbitrary fields and widgets,
-        and have their values appear formatted in the initial
-        Description, rather than in database fields. An example of this
-        is the mozilla.org 
-        <ulink url="http://bugzilla.mozilla.org/enter_bug.cgi?format=guided">guided 
-        bug submission form</ulink>.
-      </para>
-
-      <para>
-        To make this work, create a custom template for 
-        <filename>enter_bug.cgi</filename> (the default template, on which you
-        could base it, is <filename>create.html.tmpl</filename>),
-        and either call it <filename>create.html.tmpl</filename> or use a format and
-        call it <filename>create-&lt;formatname&gt;.html.tmpl</filename>.
-        Put it in the <filename class="directory">custom/bug/create</filename>
-        directory. In it, add widgets for each piece of information you'd like
-        collected - such as a build number, or set of steps to reproduce.
-      </para>
-
-      <para>
-        Then, create a template like 
-        <filename>custom/bug/create/comment.txt.tmpl</filename>, also named
-        after your format if you are using one, which
-        references the form fields you have created. When a bug report is
-        submitted, the initial comment attached to the bug report will be
-        formatted according to the layout of this template.
-      </para> 
-
-      <para>
-        For example, if your enter_bug template had a field
-        <programlisting>&lt;input type="text" name="buildid" size="30"&gt;</programlisting>
-        and then your comment.txt.tmpl had
-        <programlisting>BuildID: [% form.buildid %]</programlisting>
-        then
-        <programlisting>BuildID: 20020303</programlisting>
-        would appear in the initial checkin comment.

-      <title>Configuring Bugzilla to Detect the User's Language</title>
-
-      <para>Begining in version 2.18<![%bz-devel;[ (first introduced in version 
-      2.17.4)]]>, it's now possible to have the users web browser tell Bugzilla
-      which language templates to use for each visitor (using the HTTP_ACCEPT
-      header). For this to work, Bugzilla needs to have the correct language
-      templates installed for the version of Bugzilla you are using. Many
-      language templates can be obtained from <ulink 
-      url="http://www.bugzilla.org/download.html#localizations"/>. Instructions
-      for submitting new languages are also available from that location.
-      </para>
-
-      <para>After untarring the localizations (or creating your own) in the 
-      <filename class="directory">[Bugzilla_Root]/template</filename> directory,
-      you must update the <option>languages</option> parameter to contain any
-      localizations you'd like to permit. You may also wish to set the
-      <option>defaultlanguage</option> parameter to something other than
-      <quote>en</quote> if you don't want Engish to be the default language.

-        This feature should be considered experimental; the Bugzilla code you
-        will be changing is not stable, and could change or move between 
-        versions. Be aware that if you make modifications to it, you may have
-        to re-make them or port them if Bugzilla changes internally between
-        versions.

-      Companies often have rules about which employees, or classes of employees,
-      are allowed to change certain things in the bug system. For example, 
-      only the bug's designated QA Contact may be allowed to VERIFY the bug.
-      Bugzilla has been
-      designed to make it easy for you to write your own custom rules to define
-      who is allowed to make what sorts of value transition.

-      For maximum flexibility, customizing this means editing Bugzilla's Perl 
-      code. This gives the administrator complete control over exactly who is
-      allowed to do what. The relevant function is called 
-      <filename>CheckCanChangeField()</filename>,
-      and is found in <filename>process_bug.cgi</filename> in your 
-      Bugzilla directory. If you open that file and grep for 
-      "sub CheckCanChangeField", you'll find it.
-    </para>
-    
-    <para>
-      This function has been carefully commented to allow you to see exactly
-      how it works, and give you an idea of how to make changes to it. Certain
-      marked sections should not be changed - these are the "plumbing" which
-      makes the rest of the function work. In between those sections, you'll
-      find snippets of code like:
-      <programlisting>    # Allow the owner to change anything.
-    if ($ownerid eq $whoid) {
-        return 1;
-    }</programlisting>
-      It's fairly obvious what this piece of code does.
-    </para>      
-      
-    <para>
-      So, how does one go about changing this function? Well, simple changes
-      can be made just be removing pieces - for example, if you wanted to 
-      prevent any user adding a comment to a bug, just remove the lines marked
-      "Allow anyone to change comments." And if you want the reporter to have
-      no special rights on bugs they have filed, just remove the entire section
-      which refers to him.
-    </para>
-    
-    <para>
-      More complex customizations are not much harder. Basically, you add
-      a check in the right place in the function, i.e. after all the variables
-      you are using have been set up. So, don't look at $ownerid before 
-      $ownerid has been obtained from the database. You can either add a
-      positive check, which returns 1 (allow) if certain conditions are true,
-      or a negative check, which returns 0 (deny.) E.g.:
-      <programlisting>    if ($field eq "qacontact") {
-        if (Bugzilla->user->groups("quality_assurance")) {
-            return 1;
-        } 
-        else {
-            return 0;
-        }
-    }</programlisting>
-      This says that only users in the group "quality_assurance" can change
-      the QA Contact field of a bug. Getting more weird:
-      <programlisting>    if (($field eq "priority") &&
-        (Bugzilla->user->email =~ /.*\@example\.com$/))
-    {
-        if ($oldvalue eq "P1") {
-            return 1;
-        } 
-        else {
-            return 0;
-        }
-    }</programlisting>
-      This says that if the user is trying to change the priority field,
-      and their email address is @example.com, they can only do so if the
-      old value of the field was "P1". Not very useful, but illustrative.
-    </para>

-    <para>
-      For a list of possible field names, look in 
-      <filename>data/versioncache</filename> for the list called 
-      <filename>@::log_columns</filename>. If you need help writing custom
-      rules for your organization, ask in the newsgroup.
