How to set A4?

[ubuntu@…]

I read in the pisa docs that I can change the default paper size from A6 to A4 with a CSS section like this:

@page {
  size: a6 portrait;
  margin: .5in;
}

But where? What file do I edit? Where do I put the css file in my Trac project dir?

I would prefer to just edit the default file. Is it in a Python Egg?

A simple three-line example (showing file name, path, and procedure) would really help.

Hi, see ​Usage Instruction section. There you can specify a path or URL to a CSS file (general, or additional CSS for books or articles).

You can put the Pisa specific CSS directives in those files.
