Openbabel is a program and library designed to interconvert between many file formats used in molecular modeling and computational chemistry. The command-line utility that comes with OpenBabel is meant to be a replacement for the original 'babel' program, to translate between various chemical file formats. The library includes the file-translation code as well as utilities to help develop other free software chemistry software.
