Please make sure that the tool that creates the credentials stores them in
a mode 0600 file.  The API examples[1] do not mention this, and I think
it's an important bit of protection.

While playing with lplib for security team work, I took this a step
further and even make the directory unreadable.  e.g.:

    cachedir = os.path.expanduser('~/.launchpadlib/cache')
    if not os.path.exists(cachedir):
        os.makedirs(cachedir,0700)

    credfile = os.path.expanduser('~/.launchpadlib/credentials')
    try:
        credentials = Credentials()
        credentials.load(open(credfile))
        launchpad = Launchpad(credentials, EDGE_SERVICE_ROOT, cachedir)
    except:
        launchpad = Launchpad.get_token_and_login(sys.argv[0], EDGE_SERVICE_ROOT, cachedir)
