2002-06-25 - v1.3.2:

	* added support for openssh 2.9 (it changed ssh-add output.)

2001-04-21 - v1.3:
	* search for progs in PATH rather than hard coded /usr/bin/.

	* look for .ssh or .ssh2 dir
	* improved error messages when running a subprogram fails.
	* don't assume / path sep (dunno if ssh-multiadd is likely to be useful
	  on any systems where it isn't, but its The Right Thing To Do)
