The REUSE tool helps you achieve and confirm license compliance with the REUSE specification, a set of recommendations for licensing Free Software projects. REUSE makes it easy to declare the licenses under which your works are released, especially when reusing software from different projects released under different licenses. It avoids reliance on fuzzy heuristicts and allows both legal experts and computers to understand how your project is licensed. This allows generating a "bill of materials" for software.

This tool downloads full license texts, adds copyright and license information to file headers, and contains a linter to identify problems. There are other tools that have a lot more features and functionality surrounding the analysis and inspection of copyright and licenses in software projects. This one is designed to be simple.

Regexp::Pattern is a convention for organizing reusable regex patterns.

Licenseheaders is a Python 3 tool to update, change or add license headers to all files of any of the supported types in or below some directory.

String::Copyright Parses common styles of copyright statements and serializes in normalized format.

String::License identifies license statements in a string and serializes them in a normalized format.

Licensecheck attempts to determine the license that applies to each file passed to it, by searching the start of the file for text belonging to various licenses.

The Open Lighting Architecture is a framework for lighting control information. It supports a range of protocols and over a dozen USB devices. It can run as a standalone service, which is useful for converting signals between protocols, or alternatively using the OLA API, it can be used as the backend for lighting control software. OLA runs on many different platforms including ARM, which makes it a perfect fit for low cost Ethernet to DMX gateways.
