Templating systems for single developers?

Hi All, Given that templating seems to be a hot topic at the moment, I'm wondering if anyone here uses templating in a single developer environment, and why if so? I've looked at various template systems from time-to-time but I've always come away thinking, 'yep, I can see the point in a team environment, particularly one that mixes designers and coders, but what would be the benefit to a lone developer like me?' So, if anyone out there uses a templating system (ie Smarty, PHPSavant etc) and they don't work in a team environment, I'd love to hear what benefits you derive from so doing. Much warmth, Murray
