# Do blobless partial clones of submodules to save time and space.
# If available, do blobless partial clones of submodules to save time and space.
# A blobless partial clone lazily fetches data as needed, but has all the metadata available (tags, etc.)
# so it does not have the idiosyncrasies of a shallow clone.
#
# If not available, do a fetch that will fail, and then fix it up with a second fetch.
# (Only works for git servers that allow sha fetches.)

# NOTE: Ideally, use git version 2.36.0 or later, to do partial clones of submodules.
# If an older git is used, submodules will be cloned with a shallow clone of depth 1.
# You will see a git usage message first if the git version is too old to do
# clones of submodules.
