The document discusses requirement pattern management tools PABRE-Man and PABRE-Proj. PABRE-Man allows users to manage a repository of requirement patterns (SRPs) through classification schemas and metrics. PABRE-Proj allows users to manage projects by creating requirements that either instantiate SRPs or are specified freely, and generates requirement books. Both tools provide browsing and editing of SRPs and project requirements.
