Therion's support for importing Compass PLT files is provided by the
"img" library from Survex, which primarily provides reading and writing
of .3d files, but can also read Survex .pos files, Compass PLT, and
CMAP XYZ files.  The syntax should be the same except for the filename
extension.

If there are other formats people would find it useful to be able to
read, it's probably not hard to add support for them.
