                                                          Description

This is a simple script to send an instant msg to the webmaster. It does this by producing a temporary text file, then
scheduling an AT job, which will launch a batch file, which on its turn launches Notepad that shows the text file. After
closing Notepad, the text file is automatically deleted by the batch file.
This script only works on Windows NT, but I guess with some tweaks it could also be made working on any UNIX/Linux flavor
(with cron and some text editor like Emacs, or hell, if you'd like with VI :-|).

                                                         Installation

To install, take the following steps:

1. Make a directory to hold the batch file (showmsg.cmd, you'll make it in a minute) and (temporary) text files.
2. Make an empty text file and put the following three lines in it:
   @echo off
   %windir%\notepad.exe %1
   del %1
3. Save it as showmsg.cmd in the directory you've just created.
4. Download this PHP file (the one you're reading now) and put it wherever you like on your web site, as long as it is
   reachable from the web (of course) and you can execute PHP files in that directory.
5. Edit the variables below.
6. Done!

1.02  March 13, 2000          Now the msg contains also date & time, just in case you weren't there, so
                              you know what hit you when.
1.01  March 7, 2000           Fixed small (stupid) bug.
1.0   March 7, 2000           First release.

You have to set the following variables to the right values (don't forget the double backslashes in $workdir and
$wd_short and also make sure $workdir and $wd_short end with double backslashes!):

$workdir = "C:\\somewhere\\";                      # The directory created for the batch and text files.
$wd_short = "C:\\SOMEWH~1\\";                      # The same, but now in 8.3 format.
$delay = 5;                                        # Number of seconds the script has to delay before Notepad is opened (if
                                                   # it doesn't work and you see AT jobs being added with an execution date
                                                   # of tomorrow, you have to increase this number).
$text = "Message from \"%s\" (on ";                # Leave as-is, or change it to whatever you like, just leave two %s in
$text .= date("F j, Y  G:i:s")."):\r\n\r\n%s";     # here (the first is the e-mail address, the second the message).
