- Two-pass  data is  data that  can be accessed  before it  has been
- created.

+ Two-pass data is data that is  saved to an external file (the .tuc
+ file)  instead of  being used  directly.  The reason  is that  the
+ information might not be present at that point. One example is the
+ page counter.  It's possible  to print the  total amount  of pages
+ onto the first page.

Otherwise delete the introduction  entirely. Everyone tinkering with
that  knows what  two-pass  data  is, otherwise  he  would just  use
\setvariables, right?
