    <para>	 You can use the "setperl.csh" utility to quickly and

  <section id="cmdline">
    <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>
    </para>

      Akkana says she has good results piping buglist output through

  <section id="quicksearch">
    <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. <ulink
		       url="http://bugzilla.mozilla.org/show_bug.cgi?id=70907">This bug</ulink> has details.
