# This class is an artifact of a time when common repository operations were
# performed by calling out to scripts in the gitlab-shell project. Now, these
# operations are all performed by Gitaly, and are mostly accessible through
# the Repository class. Prefer using a Repository to functionality here.
#
# Legacy code relating to namespaces still relies on Gitlab::Shell; it can be
# converted to a module once https://gitlab.com/groups/gitlab-org/-/epics/2320
# is completed. https://gitlab.com/gitlab-org/gitlab/-/issues/25095 tracks it.
