gyoto 1.4.4-8build2 (amd64 binary) in ubuntu lunar

 Gyoto is a framework for computing geodesics in curved
 space-times. The gyoto utility program uses this framework to compute
 images of astronomical objects in the vicinity of compact objects
 (e.g. black-holes). Such images are distorted by strong gravitational
 lensing. The gyoto program takes a scenery description in XML format,
 computes this scenery using relativistic ray-tracing, and saves the
 result in FITS format.
 .
 This metapackage depends on all the Gyoto interfaces (command-line,
 Python 3 and Yorick).
 .
 MPI parallelization requires the mpi-default-bin package. The Gyoto
 documentation is provided in the gyoto-doc package.
