Revision history for Perl extension Net::SSH::Expect.

1.02 2007/08/03 
	- API changes:
		- waitfor() does not returns in list context anymore, it only returns boolean.
		- created methods before(), match() and after() to get the info about the match
		operation done by waitfor().
		- waitfor() accepts the optional paramenters '-re' and '-ex' to say if string
		must be matched as a pattern or literal string.
	- Bug fix:
		- peek() now will run a new expect() if it detects that there is data on
		$exp->after(). This wasn't done before. Without it peek() could print data that
		is not in the expect accumulator anymore.
	- Implementation improvements:
		- created a _secExpect() method, stands for "secure expect". It replaces expect().
		It croaks according to the errors it finds when it is reading from the input stream.
		All the methods that used to run expect() directly now run _secExpect().
	- Documentation improvement.

	- Implementing a total new API. Many old methods dissapeared and new methods appeared.

	on the internet required.

	- fixed the bug to set the remote prompt in the connect() method by putting the pattern
	[\s\S]+ in the expect that swallows the remote prompt
		while ($ssh->expect($timeout, '-re', qr/[\s\S]+/s)){
				# First we swallow any output the SSH server put on the tty after the logon. This is
				# usually the original remote prompt that we want to substitute.
		}

	- added the new constructor options that configure the Expect object:
	exp_internal debug

	- removed the 'verbose' attribute replacing it by two more specific attributes
	verbose_ssh and log_stdout
