"""Common functions for topology building --- :mod:`MDAnalysis.topology.core`
==========================================================================

The various topology parsers make use of functions and classes in this
module. They are mostly of use to developers.

See Also
--------
:mod:`MDAnalysis.topology.tables`
  for some hard-coded atom information that is used by functions such as
  :func:`guess_atom_type` and :func:`guess_atom_mass`.
