The minimal configuration required for pricing (market data, todays market, curve config, conventions).
Coverage note: the pricingengine.xml in this minimal example covers only Swap / swaption / capfloor / cross-currency / FX products. Engines for Bond, BondOption, BondTRS, ForwardBond, CallableBond, ... are not configured here. For those, take the engine definitions from shared/pricingengine.xml or examples/products/input/pricingengine.xml.
