# Description
This moves our `internal/{log/util/xslices}` packages out of the gotosocial repo and internal our external `code.superseriousbusiness.org/gopkg` repo. But it maintains an `internal/gtslog` subpkg for initialization of our logging configuration and syslog specifics (which aren't included in the external repo).
