if I completely understood how acpypi works, it seems that it generates the
topology parameters from the pdb file of the molecule.
But the problem is that I have the topology parameters (my angles, bond
distances and dihedrals) and want to implement them in Gromacs, so actually
I want to set specific parameters' values in gromacs.
