Actually, your synopsis is good.
I hate it when people does this; make me think. I think too much already. I'm not good at that.
*sigh*
How many times have I discovered that I've cut corners with TT, in the rush to implement / fix some borken functionality, brought more logic into the templates than I meant. It always sneaks in, because it's possible and convenient.
I've read your synopsis, quickstart and what has been written here so far today, and I will give your HTML::Seamstress a spin the next week.
