[Rd] R CMD <custom>?

[Hadley Wickham]

It'd be cool if R CMD was user extensible through packages, so that (e.g.)

R CMD mypackage::mycommand

would do something like:

path <- system.file("cmd", paste(command, ".r"), package = package)
if (!file.exists(path)) {
  stop("Command ", command, " in ", package, " does not exist")
} else {
  source(path)
}

And maybe `R CMD mypackage` would look in mypackcage/cmd/default.r.
