**ChemTensor** is a implementation of tensor network algorithms tailored for chemical systems. It is
written in C, offering a Python 3 interface for more straightforward accessibility.

Features include representation of common Hamiltonians as MPOs (including molecular Hamiltonians),
tree tensor network topologies, general MPO and TTNO construction with optimized bond dimensions
from a list of operator chains, U(1) and SU(2) symmetries, single- and two-site DMRG algorithm,
tensor hypercontraction form of molecular Hamiltonians, Basis-Update and Galerkin (BUG)
rank-adaptive time integration.
