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.

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.

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

Regexp::Pattern::License provides a hash of regular expression patterns related to legal software licenses.

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

This package provides templated software 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.

Belcard is a C++ library to manipulate VCard standard format.

Liblinphone is a high-level SIP library integrating all calling and instant messaging features into an unified easy-to-use API. It is the cross-platform VoIP library on which the Linphone application is based on, and that anyone can use to add audio and video calls or instant messaging capabilities to an application.

MSSILK is a plugin of MediaStreamer, adding support for AMR codec. It is based on the Skype's SILK implementation.

BCUnit is a fork of the defunct project CUnit, with several fixes and patches applied. It is a unit testing framework for writing, administering, and running unit tests in C.

Belle-sip is a modern library implementing SIP transport, transaction and dialog layers. It is written in C, with an object-oriented API. It also comprises a simple HTTP/HTTPS client implementation.

oRTP is a C library implementing the RTP protocol. It implements the RFC 3550 standard.

LIME is an encryption library for one-to-one and group instant messaging, allowing users to exchange messages privately and asynchronously. It supports multiple devices per user and multiple users per device.

Mediastreamer2 is a powerful and lightweight streaming engine for telephony applications. This media processing and streaming toolkit is responsible for receiving and sending all multimedia streams in Linphone, including media capture, encoding and decoding, and rendering.
