From: Ansgar Burchardt Date: Wed, 10 Apr 2013 21:04:00 +0000 (+0200) Subject: Remove dak/metadata.py and daklib/metadata.py. X-Git-Url: https://git.decadent.org.uk/gitweb/?a=commitdiff_plain;h=f0f02944f8a5744e3f10989c3afb53af2753bc15;p=dak.git Remove dak/metadata.py and daklib/metadata.py. dak imports package metadata at installation time for some time already. There is no longer need for an extra subcommand to do so. --- diff --git a/dak/metadata.py b/dak/metadata.py deleted file mode 100755 index b4c1d585..00000000 --- a/dak/metadata.py +++ /dev/null @@ -1,117 +0,0 @@ -#!/usr/bin/env python -""" -Import data for Package/Sources files from .deb and .dsc files -@copyright: 2011 Torsten Werner -@copyright: 2011 Mark Hymers -@license: GNU General Public License version 2 or later -""" - -################################################################################ - -# This program is free software; you can redistribute it and/or modify -# it under the terms of the GNU General Public License as published by -# the Free Software Foundation; either version 2 of the License, or -# (at your option) any later version. - -# This program is distributed in the hope that it will be useful, -# but WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
