-#
-# v2 layout: .git/svn/$id/info/url, refs/remotes/$id

-# - info/url may remain for backwards compatibility
-# - this is what we migrate up to this layout automatically,

-# v3.1 layout (auto migrated):
-# - .rev_db => .rev_db.$UUID, .rev_db will remain as a symlink
-# for backwards compatibility
-#
-# v4 layout: .git/svn/$repo_id/$id, refs/remotes/$repo_id/$id
-# - this is only created for newly multi-init-ed
-# repositories. Similar in spirit to the
-# --use-separate-remotes option in git-clone (now default)
-# - we do not automatically migrate to this (following
-# the example set by core git)
-#
-# v5 layout: .rev_db.$UUID => .rev_map.$UUID
-# - newer, more-efficient format that uses 24-bytes per record
-# with no filler space.
-# - use xxd -c24 < .rev_map.$UUID to view and debug
-# - This is a one-way migration, repositories updated to the
-# new format will not be able to use old git-svn without
-# rebuilding the .rev_db. Rebuilding the rev_db is not
-# possible if noMetadata or useSvmProps are set; but should
-# be no problem for users that use the (sensible) defaults.
