# Detailed description:
|
|
# This script attempts to download the source package in the same
|
|
# way as dget does, but from launchpadlibrarian.net, which doesn't
|
|
# store all the files in the same directory. It (the script) assumes
|
|
# that the files are stored in sequential directories on Launchpad
|
|
# Librarian and attemps to download and then unpack them.

print the commands it would run otherwise.
