This document accompanies the software deliverable D15 (Software Tools for Ontology
Design and Maintenance) of the TONES project, providing an overview of the delivered
software packages along with some basic information on how to install and run them. The delivered software tools are implementations of the techniques described in deliverable D13, usually enriched with optimization techniques in order to make them more
efficient. In this document, we focus on describing the relevance of the delivered tools for ontology design and maintenance. The contributions of the delivered tools to other workpackages will be the subject of later documents.
