I guess this can be done after the “install” part is written, but…

…it might be useful to have the “install” function return a handle (via some
opaque type) that can then be passed to the “launch” function. This could help
the “launch” function find the copy of Chrome that was just installed.

This is an excellent suggestion, wil do.
