/**
 * @file ck2cti.cpp
 * $Id$
 *
 * Program to convert Chemkin-II-format reaction mechanism files to
 * Cantera input format. The resulting Cantera input file contains a
 * definition of one ideal_gas entry that represents an ideal gas
 * mixture corresponding to the Chemkin-II reaction mechanism.  The
 * file also contains Cantera-format definitions for each species and
 * each reaction in the input reaction mechanism file.
 *
 * Usage: ck2cti -i input -t thermo -tr transport -id idtag
 *
 * The Cantera-format text is written to the standard output.
 *
 * @param input Chemkin-II reaction mechanism file to be converted. Required.
 *
 * @param thermo Thermodynamic property database. If the THERMO section of the 
 * input file is missing or does not have entries for one or more species,
 * this file will be searched for the required thermo data. This file may 
 * be another reaction mechanism file containing a THERMO section, or
 * a Chemkin-II-compatible thermodynamic database file.
 *
 * @param transport Transport property database. If this file name is supplied,
 * transport property parameters will be taken from this file and 
 * included in the output Cantera-format file. If this parameter is omitted, 
 * no transport property parameters will be included in the output.
 *
 * @param id idtag. The ideal_gas entry in the Cantera-format output 
 * has name \i idtag. If this parameter is omitted, it will be set to the
 * input file name without the extension. Since only one phase definition
 * is present in the ck2cti output, this parameter is not required.
