+    SOURCE except that certain files will be converted as largefiles:
+    specifically, any file that matches any PATTERN *or* whose size is
+    above the minimum size threshold is converted as a largefile. The
+    size used to determine whether or not to track a file as a
+    largefile is the size of the first version of the file. The
+    minimum size can be specified either with --size or in
+    configuration as ``largefiles.size``.
+
+    After running this command you will need to make sure that
+    largefiles is enabled anywhere you intend to push the new
+    repository.
+
+    Use --tonormal to convert largefiles back to normal files; after
+    this, the DEST repository can be used without largefiles at all.'''
