std::string tdtMolSupplierClassDoc="A class which supplies molecules from a TDT file.\n \
\n \
Usage examples:\n \
\n \
1) Lazy evaluation: the molecules are not constructed until we ask for them:\n \
>>> suppl = TDTMolSupplier('in.smi')\n \
>>> for mol in suppl:\n \
... mol.GetNumAtoms()\n \
\n \
2) Lazy evaluation 2:\n \
>>> suppl = TDTMolSupplier('in.smi')\n \
>>> mol1 = suppl.next()\n \
>>> mol2 = suppl.next()\n \
>>> suppl.reset()\n \
>>> mol3 = suppl.next()\n \
# mol3 and mol1 are the same: \
>>> MolToSmiles(mol3)==MolToSmiles(mol1)\n \
\n \
3) Random Access: all molecules are constructed as soon as we ask for the\n \
length:\n \
>>> suppl = TDTMolSupplier('in.smi')\n \
>>> nMols = len(suppl)\n \
>>> for i in range(nMols):\n \
... suppl[i].GetNumAtoms()\n \
\n \
Properties in the file are used to set properties on each molecule.\n\
The properties are accessible using the mol.GetProp(propName) method.\n\
