Open Source Software
Open source software that must be distributed with source code included or easily available, such as by free download from the Internet .
The source code should be in the same form that a programmer would actually use to maintain it – not, for instance, a generated, obfuscated, or intermediate code form. The license of this software will not restrict others from distributing the code or modifications and derived works under the same terms .
