I intend to orphan the field3d package. The MIA team has requested to
updated the uploader list, but there is only a single one, so I am going
to make a QA upload an move it out of the phototools team.

Ther are no reverse dependencies in Debian.

The package description is:
 Field3D is an open source library for storing voxel data.
 .
 It provides C++ classes that handle in-memory storage and a file format
 based on HDF5 that allows the C++ objects to be written to and read from
 disk.
