It is intended to be executed as much as possible in an automatic mode and to deliver instrument signature corrected data. Pipeline processing will be available for a subset of the VLT instrument modes. The Quality Control system includes the tools used inside and outside the pipeline environment in order to control the conditions in which the data have been acquired and processed, in particular the instrumental and observational conditions. The Quality Control Library contains a number of main classes to build these tools. A number of simulators and calibration database management tools have been developed to support proposal observing run preparations.
