A modular approach to the next-generation light source is described. The ``modules'' include photocathode, radio-frequency electron guns and their associated drive laser systems, linear accelerators, bunch compression systems, seed laser systems, planar undulators, high-gain harmonic generation systems (each composed of a modulative section, a dispersive section, and a radiative section), nonlinear ``parasitic'' harmonics, and imprinting/wavelength shifting. Combinations of these modules will be helpful in tailoring the designs of next-generation light sources to the specific needs of many more laboratories than the current designs permit, due to both monetary and/or physical space constraints.
