ddtp [SCRIPT]: merging translations with english package description files

[Jens Seidel <tux-master@web.de>]

Hi all,

I wrote a small script which simplifies the usage of translated package 
descriptions. Please see the comments in it for details.

Feel free to use and distribute it.

# This script inserts (in most cases translated) package descriptions 
from the
# first file into the second and writes the result to stdout.

# This is more useful than
#   http://ddtp.debian.org/aptable de/unstable main
# at the beginning of /etc/apt/sources.list, because APT doesn't try to 
fetch
# files (which may be more up to date) from ddtp.debian.org/ but uses the 
local
# ones.

# Package files can be found in /var/lib/apt/lists/.

# Application: Assume translated package files can be found in
# ~/dists/de/woody/main/binary-i386/Packages:
#
# cd /var/lib/apt/lists
# for i in $(ls *Packages); do
#  mv $i /tmp
#  change-pkg-description ~/dists/de/woody/main/binary-i386/Packages 
/tmp/$i > $i
# done
