        !             5:  * Build (install) COHERENT on a system, part 1.
        !             6:  * The second part of the install procedure is in install.c.
        !             7:  * Uses common routines in build0.c,
        !             8:  * serial number checking in numtab.c and serialno.c.
        !             9:  * Requires floating point output: cc build.c build0.c numtab.c serialno.c -f
        !            10:  * Usage: build [ -dv ]
        !            11:  * Options:
        !            12:  *     -d      Debug, echo commands without executing
        !            13:  *     -v      Verbose

        !            17:  * the build disk from which this program runs must contain:

        !            19:  *     In /conf:       boot, mboot, patch
        !            20:  *     In /dev:        at[01][abcdx], rat[01][abcd]
        !            21:  *     In /etc:        ATclock, badscan, fdisk, mkdev, mkfs, mount, umount
        !            22:  * It must also contain directories /mnt and /tmp.

        !            24:  * boot disk, so it writes only to directory /tmp (mounted on a RAM disk).
