        to the index. 

        :param items:
            Multiple types of items are supported, types can be mixed within one call.
            Different types imply a different handling. File paths may generally be
            relative or absolute.

            - path string
                strings denote a relative or absolute path into the repository pointing to
                an existing file, i.e. CHANGES, lib/myfile.ext, '/home/gitrepo/lib/myfile.ext'.

                Paths provided like this must exist. When added, they will be written
                into the object database.

                PathStrings may contain globs, such as 'lib/__init__*' or can be directories
                like 'lib', the latter ones will add all the files within the dirctory and
                subdirectories.

                This equals a straight git-add.

                They are added at stage 0

            - Blob or Submodule object
                Blobs are added as they are assuming a valid mode is set.
                The file they refer to may or may not exist in the file system, but
                must be a path relative to our repository.

                If their sha is null ( 40*0 ), their path must exist in the file system
                relative to the git repository as an object will be created from 
                the data at the path.
                The handling now very much equals the way string paths are processed, except that
                the mode you have set will be kept. This allows you to create symlinks
                by settings the mode respectively and writing the target of the symlink
                directly into the file. This equals a default Linux-Symlink which
                is not dereferenced automatically, except that it can be created on
                filesystems not supporting it as well.

                Please note that globs or directories are not allowed in Blob objects.

                They are added at stage 0

            - BaseIndexEntry or type
                Handling equals the one of Blob objects, but the stage may be
                explicitly set. Please note that Index Entries require binary sha's.

            As opposed to the git-add command, we enable this flag by default

            they might be excluded.

            Please note that the processed path is not guaranteed to be present
            in the index already as the index is currently being processed.

        :param path_rewriter:
            Function with signature (string) func(BaseIndexEntry) function returning a path
            for each passed entry which is the path to be actually recorded for the

            is not identical to the layout of the actual files on your hard-disk.
            If not None and ``items`` contain plain paths, these paths will be
            converted to Entries beforehand and passed to the path_rewriter.

                If True, the index will be written once it was altered. Otherwise
