i *have* read that file and, after grepping through the source tree,
i'm still confused. as a simple example, consider the possible
variables for assembler flags. so far, i've found occurrences of:
* AFLAGS
* EXTRA_AFLAGS
* ASFLAGS
* AFLAGS-y
* KBUILD_AFLAGS
* aflags-y
* asflags-y
* extra-aflags-y
should i continue? and you're suggesting that reading that docs file
is going to clarify all of this? really? good luck.
