When I run the following, psql chokes on several lines:

psql -h localhost -U postgres -f code01.sql

When I see things like <start id... and <co id... in the sample code, I really don't recognize them. Are they for some tool that I don't know about?
It's still a problem with the version of http://www.manning-source.com/books/ingersoll/tamingText-src.tar.gz available today.
