Using github to install a particular version of a package, e.g. rcall, (on Windows, Stata 15) leaves behind an rcall-X.X.X folder extracted from the zip file. It would be good to have an option to delete this after installation, especially as this folder has the dynamic element of the version (e.g. "stable" -> "3.0.7"). If I'm using github in a script, it would be hard for the script to know the version always and delete the folder programmatically. It might even be good to have this option by default.
