webq_jinja()
  Web service for sagator's quaratine access.
  
  This service can be used to access email collected by sagator via
  web interface.
  
  Requirements: python-jinja2 or python-jinja
  
  Usage: webq_jinja(host='0.0.0.0', port=8008, db,
                    log='/var/log/sagator/webq.log',
                    scanner, userconv)
  
  Where: host is an string, which defines IP address to bind,
           default: 0.0.0.0
         port is an integer, which defines tcp port to listen, default: 8008
         db is a database connection. For description see Databases.txt.
         log is defining a log file name, by default /var/log/sagator/webq.log
         scanner is a scanner to use for checking (only one scanner
           can be used here and it must be a buffer scanner!)
         userconv is an array, which defines regular expression
           and substitution strings. Usernames from login prompt
           are matched against this regular expression and substitued
           by substitution string.
         request_handler is an SimpleHTTPRequestHandler class.
           By default webq_jinja_request_handler is used.
           Use this class as parent if you need to override some functions.
           This parameter was introduced in sagator 1.3.
  
  It is recommended to use apache mod_proxy module to redirect standard
  web traffic from port 80 to webq()'s 8008. For example:
      ProxyPass /webq http://localhost:8008
      ProxyPassReverse /webq http://localhost:8008
  
  Example: See default config file for example.
