Parses a URL string and converts it into a Source.

Converts a Lua variable into a Source.

• Parses it if it’s a string.
• Returns an empty array if it’s nil.
• Will try to parse it as an array of strings otherwise. Things will probably go wrong at this point, however.

Sources can be safely converted to debug strings that will show @{protocol}, @{url} and @{filename}.

Downloads a source.

Access to a @{Context} is needed to obtain pkg++ modules and downloader backends, as well as the configuration of which directories should store the sources.
