"""Read osc configuration and store it in a dictionary
This module reads and parses ~/.oscrc. The resulting configuration is stored
for later usage in a dictionary named 'config'.
The .oscrc is kept mode 0600, so that it is not publically readable.
This gives no real security for storing passwords.
If in doubt, use your favourite keyring.
Password is stored on ~/.oscrc as bz2 compressed and base64 encoded, so that is fairly
large and not to be recognized or remembered easily by an occasional spectator.
If information is missing, it asks the user questions.
After reading the config, urllib2 is initialized.
The configuration dictionary could look like this:
{'apisrv': 'https://api.opensuse.org/',
'user': 'joe',
'api_host_options': {'api.opensuse.org': {'user': 'joe', 'pass': 'secret'},
'apitest.opensuse.org': {'user': 'joe', 'pass': 'secret',
'http_headers':(('Host','api.suse.de'),
('User','faye'))},
