# Re: Examples of integration between Lyx, Sage computations, and PDFLateX

Dear Murat,

This is great! I have been waiting for something like this for a long time.
I also like the Sweave-like philosophy of this. It's more transparent and
reproducible.

I am looking forward to the final release with much excitement.

Best,

Xu
