[NTG-context] Pagebreak only after stanzas

Hi, i am a fresh convert to Context from Latex and deeply impressed by it's ability to set multiple pages on one page, even doublesided ones. For setting a collection of poems I use \obeylines and \smallskip to arrange them on the page. Pagebreaks should only be possible between stanzas at the \smallskip-mark. Could somebody tell me, how to achieve this? Thanks in advance Chris
