++ * top - a top users display for Unix
++ *
++ * SYNOPSIS: For a NetBSD-1.5 (or later) system
++ *
++ * DESCRIPTION:
++ * Originally written for BSD4.4 system by Christos Zoulas.
++ * Based on the FreeBSD 2.0 version by Steven Wallace and Wolfram Schneider.
++ * NetBSD-1.0 port by Arne Helme. Process ordering by Luke Mewburn.
++ * NetBSD-1.3 port by Luke Mewburn, based on code by Matthew Green.
++ * NetBSD-1.4/UVM port by matthew green.
++ * NetBSD-1.5 port by Simon Burge.
++ * NetBSD-1.6/UBC port by Tomas Svensson.
++ * -
++ * This is the machine-dependent module for NetBSD-1.5 and later
++ * works for:
++ * NetBSD-1.6ZC
++ * and should work for:
++ * NetBSD-2.0 (when released)
++ * -
++ * top does not need to be installed setuid or setgid with this module.
++ *
++ * LIBS: -lkvm
++ *
++ * CFLAGS: -DHAVE_GETOPT -DORDER -DHAVE_STRERROR
++ *
