- Bdy() is a function which takes a geom as its argument. The
- geom is then converted to a polylist, which is compressed
- (See plconsol(3). Bdy() then counts the number of edges in
- the polylist used once and only once, and returns a vector
- object containing these edges. The precision, prec, is used
- to determine the maximum distance between vertices which may
- be considered identical. If the vertices must have
- identical coordinates, this value should be set to 0.0. It
- is generally desirable to set the value somewhat higher to
- allow for round-off error.
-
- The vector object is always black.
-
- BBBBUUUUGGGGSSSS
- The vector object is not a particularly compact
- representation of itself, since it contains many 2-vertex
- segments which could be combined into a longer polyline.

- Bdy() is part of the geomutil library; see geomutil(3) for
- information on how to link your program with this library.
