Probably even sooner than that -- 2.2.1 will be recorded as a different version than 2.2.0. > It would be important that that > program is distributed with R and possibly invoked automatically > as part of the installation process since its best not to have > to install a package in order to install package.

Putting together a simple package that does this would be nice, and would be available sooner than 2.3.0.
