- 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?
