There are a number of licenses that contain the term "binary distribution". For example, https://github.com/boostorg/beast/blob/develop/LICENSE_1_0.txt:
A simple permissive license only requiring preservation of copyright and license notices for source (and not binary) distribution.
What does this term precisely mean? Specifically, can I use shell scripts (e.g., https://github.com/boostorg/beast/blob/develop/tools/build-and-test.sh) without preservation of copyright notice? Do bash scripts count as both source and binary files? Or does "binary" mean only something produced by the equally vague term "compiler"?
