[NTG-context] I want to write a page which tells what the book is about

Hello Everybody! Can somebody help me please. I have a Title page: \starttext \startalignment[center] \blank[2*big] {\tfd How to do this in Context} \blank[3*medium] {\tfa The author} \blank[2*medium] {\tfa July 26, 2005} \blank[3*medium] \stopalignment Before the Title Page I would like to write a page about the content of the book. How can I write this? This page should be on the left side, because the Title page starts on the right page. Thanks a lot Uschi
