I have been working on an extension to gropdf to draw boxes underneath the usual output from groff. The idea is to make it easier to include coloured frames around groff content, without having to use keeps, particularly if you want the frame to extend over several pages. It can also add a backgtound colour to the "paper” gropdf uses.
Included is my first attempt at an extension to the ms macros to make it easy to include coloured frames. I have not used ms very much, nor written macros so I'd be very grateful if people more expert than me could improve it, particularly in regard to proper integration with the ms macros. The attached archive contains the new version of gropdf. Also it includes the macro extension file sboxes.tmac which can be used with "-ms -msboxes", and an example of using the extension called msboxes.ms. Please feel free to do whatever to improve it. Cheers Deri
