 * uname-a.d - "uname -a" demo in DTrace.
 *             Written using DTrace (Solaris 10 3/05).
 *
 * This has been written to demonstrate fetching the "uname -a" info
 * from a DTrace script, which turns out to be all kernel variables.
 * This is intended as a starting point for other DTrace scripts, by
 * beginning with familiar statistics.

 *
 * USAGE:	uname-a.d

 * FIELDS:	See uname(1) manpage for documentation.
