[tex-eplain] Landscape illustrations and captions

[Adam Fenn]

How can I modify the hyperlinks example (8.1) in the eplain 
documentation so that the caption appears on the right side of the 
illustration and is also centred on the illustration?
The only modification to the code I have made is to add the option 
angle=90.

Thanks,
Adam.
