From ac9dde072c56b9dbc3fe515dc3702c2c992f492f Mon Sep 17 00:00:00 2001 From: Nagy Gabor Date: Wed, 20 May 2009 21:46:23 +0200 Subject: Introduce -D, --database The request of FS#12950 is implemented. On the backend side, I introduced a new function, alpm_db_set_pkgreason(), to modify the install reason of a package in the local database. On the front-end side, I introduced a new main operation, -D/--database, which has two options, --asdeps and --asexplicit. I documented this in pacman manual. I've created two pactests to test -D: database001.py and database002.py.
