This package defines a set of Source types that represent the various sources that a BinaryBuilder2 recipe can download and use in the build, such as GitSource, ArchiveSource, JLLSource, GeneratedSource and more. Source objects all support a common API include prepare(), deploy(), content_hash() and more. See the docstrings in the package for more detail on how to use these in your own package, but as a simple example:

using BinaryBuilderSources

as = ArchiveSource(url, hash)
mktempdir() do prefix
    deploy(as, prefix)

    # Now do something with `prefix`, as the archive has been unpacked there
