-- **[ScanCode Toolkit](https://github.com/nexB/scancode-toolkit)**: This is a set of code scanning tools to detect the origin and license of code and dependencies. ScanCode now uses a plug-in architecture to run a series of scan-related tools in one process flow. This is the most popular projects and is used by 100's of software teams. https://github.com/nexB/scancode-toolkit . The lead maintainer is @pombredanne

 (formerly AboutCode Manager) This is a desktop application (based on Electron) to review the results of a scan and document your conclusions about the origin and license of software components and packages. https://github.com/nexB/aboutcode-manager . The lead maintainer is @majurg

 - **[TraceCode Toolkit](https://github.com/nexB/tracecode-toolkit)**: This is a set of tools to trace files from your deployment or distribution packages back to their origin in a development codebase or repository.  The primary tool uses strace https://github.com/strace/strace/ to trace system calls on Linux and construct a build graph from syscalls to show which files are used to build a binary. We are contributors to strace. Maintained by @pombredanne
 
 - **[Conan](https://github.com/nexB/conan)**: stands for "CONtainer ANalysis" and is a tool to analyze the structure and provenance of software components in Docker images using static analysis. https://github.com/nexB/conan Maintained by @pombredanne
 
-- **[license-expression](https://github.com/nexB/license-expression/)**: this is a library to parse, analyze, compare and normalize SPDX and SPDX-like license expressions using a boolean logic expression engine. See https://spdx.org/spdx-specification-21-web-version#h.jxpfx0ykyb60 to understand what an expression is. See https://github.com/nexB/license-expression for the code.
