       USAGE

              cdksdf2smiles < input.sdf cdksdf2smiles inputs*.sdf

   OPTIONS:-2, --mdl2000-input
              read MDL2000 format files (default)

       -3, --mdl3000-input
              read MDL3000 format files

       --cdk-electron-donation-model

              use the CDK electron donation model (requires extra automatic atom type perception)

       --daylight-electron-donation-model

              use the Daylight el. donation model (default)

       -a, --aromatic
              output "aromatic" SMILES

       -a-,--not-aromatic
              output "kekulised" SMILES

       -h, --suppress-hydrogens

              suppress explicit hydrogens (default)

       -h-, --dont-suppress-hydrogens

              leave explicit hydrogens
