It has been prepared by the editors of this volume by substantial rewriting of the DiSCiPl deliverable CP Debugging Tools [1]. This introduction is organised as follows. Section 1 outlines the DiSCiPl view of debugging, its associated debugging methodology, and motivates the kinds of tools proposed: the assertion based tools, the declarative diagnoser and the visualisation tools. Sections 2 through 4 provide a short presentation of the tools of each kind. Finally, Section 5 presents a summary of the tools developed in the project. This introduction gives only a general view of the DiSCiPl debugging methodology and tools. For details and for specific bibliographic referenees the reader is referred to the subsequent chapters.
