Bug#434390: cdbs: class for generating buildfiles from clean autotool-files

[Carl Fürstenberg <azatoth@gmail.com>]

Package: cdbs
Version: 0.4.49
Severity: wishlist
Tags: patch

Was thinking how to generate debian packages from a totally clean source
tree. So I made this class, and though perhaps it should be included
into cdbs (or in simlar form).


-- System Information:
Debian Release: 4.0
  APT prefers unstable
  APT policy: (500, 'unstable'), (1, 'experimental')
Architecture: i386 (i686)

Kernel: Linux 2.6.21-1-686 (SMP w/1 CPU core)
Locale: LANG=sv_SE.UTF-8, LC_CTYPE=sv_SE.UTF-8 (charmap=UTF-8)
Shell: /bin/sh linked to /bin/bash

cdbs depends on no packages.

Versions of packages cdbs recommends:
ii  autotools-dev                 20060920.1 Update infrastructure for config.{
ii  debhelper                     5.0.42     helper programs for debian/rules

-- no debconf information
