You can configure the template files visually using the Data Comparer Wizard. Set all the necessary options in each step of the wizard and click the Tools | Save template button. All the options will be saved to the template file which can be used afterwards in the console application.
The trial version of the utility allows to compare and synchronize no more than 10 tables. As for the rest, the functionality of the trial version does not differ from the full one. You can test the features implemented in Data Comparer within the 30-day trial period for free.
