From fa510078749917cb4225bf32a10284b905ab7603 Mon Sep 17 00:00:00 2001 From: rwatson Date: Wed, 23 Oct 2002 03:15:24 +0000 Subject: [PATCH] Introduce simple command line tools to manage MAC labels on processes and files. Basically wrappers for mac_{get,set}_{file,link,pid,proc}(3). Man pages to be updated shortly.
