  Models of gravitational waveforms from coalescing black-hole binaries play a
crucial role in the efforts to detect and interpret the signatures of those
binaries in the data of large-scale interferometers. Here we summarize recent
models that combine information both from analytical approximations and
numerical relativity. We briefly lay out and compare the strategies employed to
build such complete models and we recapitulate the errors associated with
various aspects of the modelling process.
