Advancing open source license compliance

FOSSology is an open source license compliance software system and toolkit. As a toolkit you can run license, copyright and export control scans from the command line. As a system, a database and web ui are provided to give you a compliance workflow. In one click you can generate an SPDX file, or a ReadMe with the copyrights notices from your software. FOSSology deduplication means that you can scan an entire distro, submit a new version, and only the changed files will get rescanned. This is a big time saver for large projects.
