If it’s bundled in a release, add this (or something like it) to the releases LICENSE file: "This product bundles (path to file go here) a Base64 AS3 library, copyright (C) 2012 Jean-Philippe Auclair, which is available under a MIT license. For details, see licenses/Base64AS3lib.LICENSE." The suggested way to to include a pointer to a file containing the full text of the license[1]. The file header is missing the MIT text so this need to be done in a separate file in order to comply with the terms of the MIT license. [2] i.e. The "The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.” bit. Grab the file from https://opensource.org/licenses/mit-license.php and fill in the copyright year and owners name. But there are several valid ways to do this, and different projects do it slightly differently, as long as: 1. The MIT license text is included somewhere in the release 2. LICENSE mentions what is MIT licensed 3. The original header and copyright is kept intact You have legal and ASF policy covered and everything is good. The bundled bit is the most important bit, if you add it to flex utils, anything that bundles flex utils (and made into a release) LICENSE file will need to change. So potentially it could effect more than one LICENSE file depending on what releases actually bundled the file in question.
