  We reconsider the effective Lagrangian that describes a light Higgs-like
boson and better clarify a few issues which were not exhaustively addressed in
the previous literature. In particular we highlight the strategy to determine
whether the dynamics responsible for the electroweak symmetry breaking is
weakly or strongly interacting. We also discuss how the effective Lagrangian
can be implemented into automatic tools for the calculation of Higgs decay
rates and production cross sections.
