I've been working through Polchinski on my own, and I have a really basic question. How would one derive equation 2.4.1? What does it even mean to write the stress tensor with the new indices z and zbar? I thought this was obvious, but it isn't working out for me.

clarification: this is not a homework problem, and it is not for a class.
