Getting ATLAS to use your kernel

OK, so let's say you've got a kernel that is faster than what ATLAS is presently using, how do you get ATLAS to use it? First, of course, you put the source in the CASES directory, and update the appropriate <pre>cases index file. Then, you take different steps depending on how you wish to do the install, as discussed in the following sections. In all of these discussions, <pre> is replaced by your type/precision modifier (one of s, d, c, z), and <arch> is replaced by your architecture ID (eg., Linux_PII).
