The GSI Version of Silecs is a fork of the CERN Silecs version. It was forked 2018 and has evolved into a slightly different framework. The fork was required because CERN did not merge GSI merge requests, and generally does not respect the GPL v3 licence (source code and issue tracker only visible in the CERN walled garden, CERN account and special privileges required, software only builds and runs within CERN infrastructure ). That makes a collaboration/contributions impossible.
