[NTG-context] Inserting verbatim text in a figure and framed.

Here is my code so far. I want to show a file in verbatim form. It compiles but here is no frame around the text and there is no caption. ---------------------------- \startbuffer[ex1] \typefile[]{example1.tex} \stopbuffer \placefigure[here][fig:ex1] {Example 1} {\externalfigure[ex1.buffer][width=.75\textwidth]} -------------------------------------------------- I am following the example at the foot of page 303 in the manual. Any suggestions? John Culleton
