 This repository contains 24 Java libraries developed by the SPeCS research group, organized as independent Gradle projects. Each library extends or enhances existing Java libraries (indicated by the "-Plus" suffix) or provides custom utilities. The repository uses Java 17, Gradle for builds, and follows a multi-project structure without a root Gradle configuration.
 
 **Repository Statistics:**
-- 24 main Java libraries + 3 legacy projects (RuntimeMutators, SpecsHWUtils, SupportJavaLibs)
+- 24 main Java libraries + 1 legacy project (SpecsHWUtils)
 - ~200K+ lines of Java code across all projects
 - Mixed testing frameworks: JUnit 5 (modern projects) and JUnit 4 (legacy projects)
 - Inter-project dependencies centered around SpecsUtils as the core utility library
