Here you can configure external tools which should be used instead of the built-in Conflict Solver.
You can either choose to use the Built-in Conflict Solver or an External Conflict Solver. An external conflict solver is defined by the operating system Command to be executed, and its Arguments.
Arguments are passed to the Command as it would occur from the OS command line. The place holder ${leftFile}, ${rightFile}, ${mergedFile} and ${baseFile} can be used, which will be substituted by the absolute file path of the left, right and merged (resulting) file, respectively. Furthermore, the place holder ${encoding} can be used which will be substituted by the file's used encoding. Refer to Text File Encoding for details.
