* top - a top users display for Unix
|

*
|
||||
* SYNOPSIS: For FreeBSD-2.x system
|
||||
*
|
||||
* DESCRIPTION:
|
||||
* Originally written for BSD4.4 system by Christos Zoulas.
|
||||
* Ported to FreeBSD 2.x by Steven Wallace && Wolfram Schneider
|
||||
*
|
||||
* This is the machine-dependent module for FreeBSD 2.2
|
||||
* Works for:
|
||||
* FreeBSD 2.2, and probably FreeBSD 2.1.x
|
||||
*
