- Heh. It's a fast hack, but it seems people like it a lot more than
- editing Makefiles.. Strange.

- Yes, it's the co-processor emulation code. If you have a co-processor,
- you can answer 'n' (or just press enter: the default is set up according
- to my system, which has a copro). Without a coprocessor, you should
- answer 'y' to this question.

- > kernel profiling support?
-
- Answering 'y' to this adds some small code to do limited kernel
- profiling: to actually get the information you'll have to use a special
- program that reads kmem to find out the results. This is not something
- people generally need to do: it's meant only for kernel hackers who want
- to see where the kernel spends most of its time.
-
- > /proc filesystem support?
-
- If you answer 'y' (or blank) to this, the proc-fs filesystem code is
- linked in. Do a
-
- mkdir /proc
- mount -t proc /proc /proc
-
- to find out more about it: it essentially gives some general linux
- process information (so that you can write 'ps' as a shell script or
- whatever instead of messing around with kmem).
