I don't remember if this is platform independent,  but

R CMD foo

on Windows will set up standard environment variables then try to 
execute "foo".  If "foo" isn't one of the internal commands listed by

R CMD --help

then it will just go looking for it like any other command in the path.  
(This is why "R CMD install" gives a funny error message:  the internal 
command is "INSTALL", so "R CMD install" just tries to execute "install".)
