+    /*  Blobless clone
+        ==============
+
+        When using the --filter=blob:none option, the initial git clone will
+        download all reachable commits and trees, and only download the blobs
+        for commits when you do a git checkout. This includes the first checkout
+        inside the git clone operation.
+
+        The important thing to notice is that we have a copy of every blob at
+        HEAD but the blobs in the history are not present. If your repository
+        has a deep history full of large blobs, then this option can
+        significantly reduce your git clone times. The commit and tree data is
+        still present, so any subsequent git checkout only needs to download
+        the missing blobs. The Git client knows how to batch these requests to
+        ask the server only for the missing blobs.
+
+        Further, when running git fetch in a blobless clone, the server only
+        sends the new commits and trees. The new blobs are downloaded only
+        after a git checkout. Note that git pull runs git fetch and then git
+        merge, so it will download the necessary blobs during the git merge
+        command.
+
+        When using a blobless clone, you will trigger a blob download whenever
+        you need the contents of a file, but you will not need one if you only
+        need the OID (object-id) of a file. This means that git log can detect
+        which commits changed a given path without needing to download extra
+        data.
+
+        This means that blobless clones can perform commands like git
+        merge-base, git log, or even git log -- <path> with the same performance
+        as a full clone.
+
+        Commands like git diff or git blame <path> require the contents of the
+        paths to compute diffs, so these will trigger blob downloads the first
+        time they are run. However, the good news is that after that you will
+        have those blobs in your repository and do not need to download them a
+        second time. Most developers only need to run git blame on a small
+        number of files, so this tradeoff of a slightly slower git blame command
+        is worth the faster clone and fetch times.
+
+        Note: git v2.18 does not support treeless clones: --filter=tree:0.
