HISTORY
A modstat
utility appeared in
NetBSD 0.9. The modstat
command was designed to be similar in functionality to the corresponding
command in SunOS 4.1.3. modstat
was switched to the
module framework for NetBSD 5.0.
AUTHORS
The original NetBSD implementation was written by Terrence R. Lambert <terry@cs.weber.edu>. The switch to the module framework was by Andrew Doran <ad@NetBSD.org>.
