 The main goal of Aravis is to provide a library that interfaces with industrial cameras. It also provides a set utilities that help to debug the library, namely arv-viewer-0.8, arv-tool-0.8, arv-camera-test-0.8 and arv-fake-gv-camera-0.8. The version suffix corresponds to the API version, as several stable series of Aravis can be installed at the same time.
