  # Set these variables to configure the script           #

# Set $domain to your domain name (no www)

  $domain = "test.com";
# Set $docroot to the URL of the directory which contains your

  # .htaccess file. Don't include trailing slash.

  $docroot = "http://www.test.com";
# Set $template to the full system path to the HTML file that

  # you want to use as a template. If you don't set this, the

  # script will use its default built-in template. If you create

  # your own template, place the token %OUTPUT% where you want

  # the output to appear.

# This script is capable of mailing the details of each 404 error

  # to the webmaster. Use the $reportlevel variable to control when

  # you receive these reports.

  #

  # 0 = don't use the email capabilities, just display the page

  # 1 = send email only if the error's referer contains your domain name

  #     (i.e. the 404 was generated by a broken link on your site)

  # 2 = send email any time a 404 error is generated (useful for tracking

  #     broken links at other sites which link to you)
$reportlevel = 2;
# Set $emailaddress to the email address of whoever should be

  # notified of 404 errors. Don't escape the @ symbol.

  # You can leave this unassigned if you're not using email features.
