Coming to a future release

	* Better history handling

	* Expanded history options

	* Ability to use an easier to read configuration file

	* Color

	* one or two more actions

Version 2.2

	* Now using the getopts.pl library as the command line parser instead
  	  of the non-standard library that I was using.

	* No longer writing the watcher script into a temporary file. Instead
	  I store the script internally and run it inside a child process.
	  This also fixed the bug where 2.1 did not remove the watcher script
	  upon exit.

        * Cleaned up code to follow style rules more closely

        * Reduced the history reporting to one line.

	* Updated and cleaned up installation scripts.

Version 2.1

        * Changed the "exec" action do that it returns immediately
	  after forking and execing a command.

	* Added the "system" action which essentially execs a command
	  then waits for the command to finish.

	* Corrected logic in "set_alarm" subroutine because the alarm
	  alarm would sometimes get set incorrectly.

	* Eliminated the need for system dependent Perl header files
	  by cleaning up some of my code.
