		Build Configuration
		===================

		Optional components and other build-time configuration are controlled by the `CONFIG` file
		in the root SPDK directory. `CONFIG` is a Makefile fragment that may be edited before building to
		control which options are enabled.

		Boolean (on/off) options are configured with a 'y' (yes) or 'n' (no). For example, this line of
		`CONFIG` controls whether the optional RDMA (libibverbs) support is enabled:

		CONFIG_RDMA?=n

		To enable RDMA, this line of CONFIG may be modified to contain 'y' instead of 'n'.

		Alternatively, `CONFIG` options may also be overrriden on the `make` command line:

		make CONFIG_RDMA=y

		The options specified on the `make` command line take precedence over the default values in
		`CONFIG`.
