For source packages, yes, but not for binary packages.  Here's what I have
been using; it's far from perfect, but it gets the job done in most cases.

    sys.exit(exitcode)

if versionlist == None or len(versionlist) == 0:
    sys.stderr.write("No versions available\n")
    sys.exit(1)

filelist = versionlist[0].FileList

pkgrecords.Lookup(filelist[0])
filename = pkgrecords.FileName

outfilename = os.path.basename(filename)
outfile = open(outfilename, 'w')
url = urljoin(mirror,filename)
infile = urlopen(url)

size = None
if infile.info().has_key('Content-Length'):
    size = int(infile.info()['Content-Length'])

bufsize = 8192
copied = 0

while 1:
    buf = infile.read(bufsize)
    if buf == '':
        break
    outfile.write(buf)
    copied += len(buf)

    if (time.time() - progress_update) >= 0.25:
        percent = copied * 100 / size
        if size:
            print '\r[%s %s/%s %s%%]' % (outfilename, copied, size, percent),
        else:
