I'm mainly thinking of LLVM and Ocaml. (I'm not a computer scientist.) But I fear that code transformation tools lie beyond the skill and ability of those of us who submit spelling fixes. So the tools need to be made more usable in this setting. Corporate users of kernel code who happen to have their own IDE products (Microsoft, Google, etc.) have an opportunity here. -- > Thanks > Boaz > > > Thanks, > > Bart. > >
