    <title>DESCRIPTION</title>
    <para>
        reglookup is designed to read windows registry elements and
        print them out to stdout in a CSV-like format.  It has filtering
        options to narrow the focus of the output.  This tool is
        designed to work with on windows NT/2K/XP/2K3 registries, though
        your mileage may vary.

      <!-- XXX: this should be a bit more formal -->
      <command>reglookup</command> generates a comma-separated values (CSV) 
      compatible format to stdout.  The format is designed to simplify parsing 
      algorithms of other tools by quoting CSV special characters using a 
      common hexadecimal format.  Specifically, special characters or non-ascii 
      bytes are converted to "\xQQ" where QQ is the hexadecimal value for 
      the byte.

    <title>BUGS</title>
    <para>
      This program has only been tested on a few different systems.
      (Please report results to the development list if you test it 
      on Windows NT 4.0, 2003, or Vista registries.  Also, if you 
      test on any 64-bit architecture, please contact us.)
    </para>
    <para>
      Verbose output is not working.
    </para>
    <para>
      The SID conversions haven't been carefully checked for accuracy.
    </para>
    <para>
      The MTIME conversions appear correctly produce the stored UTC timestamp.
      However, due to the periodicity of registry writes, and the complexity
      of the conversion, a small amount of error (on the order of seconds) may
      be possible.  The documentation available online from Microsoft on 
      this field is very poor.
    </para>
    <para>
      Backslashes are currently considered special characters, to make 
      parsing easier for automated tools.  However, this causes paths 
      to be difficult to read.
    </para>
    <para>
      You'll notice that registry paths aren't all the same as the
      equivalents you see in the windows registry editor.  Don't ask me why 
      that is.  I just work here.
    </para>
    <para>
      This software should be considered unstable at this time.

      This program was initially based on editreg.c by 
      Richard Sharpe.  It has since been rewritten to use a modified
      version the regfio library written by Gerald Carter.  Heavy
      modifications to the library and the original command line
      interface have been done by Timothy D. Morgan.
