add_hook

This function allows users of <code>callr</code> to specify functions that get invoked
whenever an R session is launched. The function can modify the environment
variables and command line arguments.

It is sometimes useful to perform a computation in a separate
R process, without affecting the current R process at all.  This
packages does exactly that.
