/**
 * Finger servlet. This servlet uses the finger protocol to query
 * information about users on specified hosts. The query string
 * parameters <tt>user</tt>, <tt>hosts</tt>, and <tt>verbose</tt>
 * can be used to specify the user and hosts to query. The parameter
 * <tt>user</tt> is the user name, <tt>hosts</tt> is a comma-separated
 * list of host names to query, and <tt>verbose</tt> if specified will
 * cause verbose output to be generated. For example,
 * <pre>
 *     http:/goa/finger.html?user=dac&hosts=eno,doppio&verbose=yes
 * </pre>
 * This URL will request full information about user 'dac' on both
 * hosts 'eno' and 'doppio'.
