The REUSE specifications[1] are meant to make it explicit and easier to apply code licensing information for a project. The provided lint tool makes it easy to ensure all the content (code and not code) is tagged. Important notes: * All the code (and documentation) that otherwise didn't have an explicit license headers have been tagged with ladyada's copyright as per the LICENSE file. * favicon.ico and CODE_OF_CONDUCT.md have been synced from the source-of-truth repositories. * All configuration files have been tagged with ladyada's copyright and Unlicense[2]. The current REUSE recommendation is to use CC0-1.0, but that has… side effects. There's some discussion in [3] about the recommendation for likely-uncopyrightable files (such as configuration files).
