Gyoto aims at providing a framework for computing orbits and ray-traced images in General relativity. It consists in a shared library (this package), utility programs (in the gyoto package), and a plug-in for the Python 3 and Yorick programming languages (in python3-gyoto and yorick-gyoto respectively). Gyoto can be extended with plug-ins (see libgyoto9-dev).

Includes modules for configuration file handling, error handling, logging and system information retrieval. A signal handler enables applications to do stack backtracing in case of segmentation faults.
