function add_artifact!(
    artifacts_toml::String, name::String, tarball_url::String;
    clear=true,
    platform::Union{Platform,Nothing}=nothing,
    lazy::Bool=false,
    force::Bool=false
)

Downloads tarball from tarball_url, extracts it and adds it as an artifact with name name to the file artifacts_toml. If clear is true, the artifact itself is deleted afterwards. The rest of the keyword arguments are passed to Pkg.Artifacts.bind_artifact!.

From its docstring:

If platform is not nothing, this artifact is marked as platform-specific, and will be a multi-mapping. It is valid to bind multiple artifacts with the same name, but different platforms and hash'es within the same artifacts_toml. If force is set to true, this will overwrite a pre-existant mapping, otherwise an error is raised.

[...] If lazy is set to true, even if download information is available, this artifact will not be downloaded until it is accessed via the artifact"name" syntax, or ensure_artifact_installed() is called upon it.
