By default, this compares modification time, and only stages files that need updating. If `overwrite` is specified, matching files are purged before proceeding. Parameters ---------- path : path to file, directory, zip or tarball archive, or URL to install By default, the file will be installed with its base name, so '/path/to/foo' will install to 'nbextensions/foo'. See the destination argument below to change this. Archives (zip or tarballs) will be extracted into the nbextensions directory. overwrite : bool [default: False] If True, always install the files, regardless of what may already be installed. symlink : bool [default: False] If True, create a symlink in nbextensions, rather than copying files. Not allowed with URLs or archives. Windows support for symlinks requires Vista or above, Python 3, and a permission bit which only admin users have by default, so don't rely on it. user : bool [default: False] Whether to install to the user's nbextensions directory. Otherwise do a system-wide install (e.g. /usr/local/share/jupyter/nbextensions). prefix : str [optional] Specify install prefix, if it should differ from default (e.g. /usr/local). Will install to ``/share/jupyter/nbextensions`` nbextensions_dir : str [optional] Specify absolute path of nbextensions directory explicitly. destination : str [optional] name the nbextension is installed to. For example, if destination is 'foo', then the source file will be installed to 'nbextensions/foo', regardless of the source name.
