[NTG-context] Producing EPDF

Dear All, is it possible to and howdoi produce EPDF (in mkiv if it matters). By EPDF I mean EPS like PDF, pagesize == bounding box of what is really printed with minimal or no white border. Reason to do that - produce with ConTeXt one-two line short labels for another program (Asymptote). Sincerely, Michail
