How to use WannierTools to symmetrizated Wannier Hamiltonian?

[SuHang980715]

Hi, sorry for disturbing. In the section 2.4 of the document, it talks about a new application of the tools: symmetrization of wannier90_hr.dat.
However, it seems lacking some more detailed information in this section, for example: how to write the input files in the wt.in, and how to run it?

Could you give more suggestions about this section? Thanks.
