    module lets you do some truly amazing things with URL rewriting. Here are
    a couple of examples of what you can do.</para>

        <para>Make it so if someone types 
        <computeroutput>http://www.foo.com/12345</computeroutput>

        , Bugzilla spits back http://www.foo.com/show_bug.cgi?id=12345. Try
        setting up your VirtualHost section for Bugzilla with a rule like
        this:</para>

        <programlisting>
<![CDATA[
<VirtualHost 12.34.56.78>
RewriteEngine On
RewriteRule ^/([0-9]+)$ http://foo.bar.com/show_bug.cgi?id=$1 [L,R]

      <listitem>
        <para>There are many, many more things you can do with mod_rewrite.
        As time goes on, I will include many more in the Guide. For now,

    <title>Command-line Bugzilla Queries</title>

    <para>Users can query Bugzilla from the command line using this suite of
    utilities.</para>

    <para>The query.conf file contains the mapping from options to field
    names and comparison types. Quoted option names are "grepped" for, so it
    should be easy to edit this file. Comments (#) have no effect; you must
    make sure these lines do not contain any quoted "option"</para>

    <para>buglist is a shell script which submits a Bugzilla query and writes
    the resulting HTML page to stdout. It supports both short options, (such
    as "-Afoo" or "-Rbar") and long options (such as "--assignedto=foo" or
    "--reporter=bar"). If the first character of an option is not "-", it is
    treated as if it were prefixed with "--default=".</para>

    <para>The columlist is taken from the COLUMNLIST environment variable.
    This is equivalent to the "Change Columns" option when you list bugs in
    buglist.cgi. If you have already used Bugzilla, use 
    <command>grep COLUMLIST ~/.netscape/cookies</command>

    to see your current COLUMNLIST setting.</para>

    <para>bugs is a simple shell script which calls buglist and extracts the
    bug numbers from the output. Adding the prefix
    "http://bugzilla.mozilla.org/buglist.cgi?bug_id=" turns the bug list into
    a working link if any bugs are found. Counting bugs is easy. Pipe the
    results through 
    <command>sed -e 's/,/ /g' | wc | awk '{printf $2 "\n"}'</command>

    <title>The Quicksearch Utility</title>

    <para>Quicksearch is a new, experimental feature of the 2.12 release. It
    consist of two Javascript files, "quicksearch.js" and "localconfig.js",
    and two documentation files, "quicksearch.html" and
    "quicksearchhack.html"</para>

    <para>The index.html page has been updated to include the QuickSearch
    text box.</para>

    <para>To take full advantage of the query power, the Bugzilla maintainer
    must edit "localconfig.js" according to the value sets used in the local
    installation.</para>

    <para>Currently, keywords must be hard-coded in localconfig.js. If they
    are not, keywords are not automatically recognized. This means, if
    localconfig.js is left unconfigured, that searching for a bug with the
    "foo" keyword will only find bugs with "foo" in the summary, status
    whiteboard, product or component name, but not those with the keyword
    "foo".</para>

    <para>Workarounds for Bugzilla users: 
    <simplelist>
      <member>search for '!foo' (this will find only bugs with the keyword
      "foo"</member>

      <member>search 'foo,!foo' (equivalent to 'foo OR keyword:foo')</member>
    </simplelist>
    </para>

    <para>When this tool is ported from client-side JavaScript to server-side
    Perl, the requirement for hard-coding keywords can be fixed.
