In priniciple, yes, but I haven't heard a better way of doing it
than the multiprocess dynamic program that I once outlined on this
mailing list; everyone guesses this would be too costly to run.
This is a real challe
Is there a shaping method which provides optimal spacing whilst using traps?
Hello Doug,

this is in general described in the TeXbook on page 101 for the \parshape
command.
There one can set \parshape=n i1 l1 i2
Suppose one wants to control the shape of filled text so it
fits in a figure, for example a triangle or disc. In groff
one would set a trap to change indent and/or line length on
every line. The traps could be set all at once in advance,
or more elegantly by a self-resetting trap macro.
