From ae20f8820278d285400afb7c3b7f2ba3c789c61a Mon Sep 17 00:00:00 2001 From: "Denis A. Altoé Falqueto" Date: Thu, 16 Sep 2010 00:40:35 -0300 Subject: pacman-key: keyring management tool MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The script pacman-key will manage pacman's keyring. It imports, exports, fetches from keyservers, helps in the process of trusting and updates the trust database. Signed-off-by: Denis A.
