+A [StackBlock 1.5](https://github.com/sanshar/StackBlock) compatible user interface can be found at `pyblock2/driver/block2main`.
 This script can work as a replacement of the StackBlock binary, with a few limitations and some extensions.
 The format of the input file `dmrg.conf` is identical to that of StackBlock 1.5.
 See `docs/driver.md` and `docs/source/user/basic.rst` for detailed documentations for this interface.
 Examples using this interface can be found at `tests/driver`.
