+packfiles) Git objects.  It uses the pack package to search pack index files
+and locate the corresponding delta-base chain in the appropriate pack file.
+If gitobj can't find a loose object with the appropriate SHA-1, it will search
+the repository's packfile(s) instead.  If it finds an object in a packfile, it
+will reconstruct the object along its delta-base chain and return it.")
