20 :     =head1 NMPDR Emergency Switch
21 :    
22 :     This method will rename files in the HTML root of the NMPDR website in order
23 :     to bring the NMPDR up or down. While it is down, the main page will redirect
24 :     users to the backup copy of NMPDR (the "mirror site"). The single
25 :     command-line parameter should be C<off> to turn the NMPDR off (redirecting
26 :     users to the backup web site) or C<on> to turn it back on.
27 :    
28 :     The currently-supported command-line options are as follows.
29 :    
30 :     =over 4
31 :    
32 :     =item user
33 :    
34 :     Name suffix to be used for log files. If omitted, the PID is used.
35 :    
36 :     =item trace
37 :    
38 :     Numeric trace level. A higher trace level causes more messages to appear. The
39 :     default trace level is 2. Tracing will be directly to the standard output
40 :     as well as to a C<trace>I<User>C<.log> file in the FIG temporary directory,
41 :     where I<User> is the value of the B<user> option above.
42 :    
43 :     =item sql
44 :    
45 :     If specified, turns on tracing of SQL activity.
46 :    
47 :     =item background
48 :    
49 :     Save the standard and error output to files. The files will be created
50 :     in the FIG temporary directory and will be named C<err>I<User>C<.log> and
51 :     C<out>I<User>C<.log>, respectively, where I<User> is the value of the
52 :     B<user> option above.
53 :    
54 :     =item h
55 :    
56 :     Display this command's parameters and options.
57 :    
58 :     =item phone
59 :    
60 :     Phone number to message when the script is complete.
61 :    
62 :     =back
63 :
