With nucl-th/0407060, Jacques Raynal uses the arXiv in a way which does not conform to standard professional practices. His posting contains many statements that are beyond the borders of acceptable scientific disputes, with the scope to defame colleagues by manifestly false or misleading statements. In this comment we reject the three ``critiques'' expressed by Raynal. 1. The fact that we possibly misquoted our references. 2. The role of the Pauli principle in these kind of calculations. 3. The nature and limits of our coupled-channel potential model. Raynal's postings unfairly detract from the importance of our work, which we published in Nuclear Physics A728, 65 (2003), on a new approach, Multi-Channel-Algebraic-Scattering (MCAS), for coupled-channel calculations. With the MCAS approach we were able to identify systematically all low-energy compound resonances, and to include effectively the Pauli principle in collective, geometrical-type, macroscopic models of multichannel interaction. This represents a clear advantage with respect to the current distribution of the ECIS formulation.
