This module handles configuration of osc.
Configuring osc from oscrc
--------------------------
To configure osc from oscrc, do following::
import osc.conf
# see ``get_config()`` documentation for available function arguments
# see ``oscrc(5)`` man page for oscrc configuration options
osc.conf.get_config()
Configuring osc from API
------------------------
To configure osc purely from the API (without reading oscrc), do following::
import osc.conf
# initialize the main config object
config = osc.conf.Options()
# configure host options for an apiurl
apiurl = osc.conf.sanitize_apiurl(apiurl)
host_options = HostOptions(apiurl=apiurl, username=..., _parent=config)
config.api_host_options[apiurl] = host_options
# set the default ``apiurl``
config.apiurl = ...
# place the config object in `osc.conf`
osc.conf.config = config
# optional: enable http debugging according to the ``http_debug`` and ``http_full_debug`` options
from osc.connection import enable_http_debug
enable_http_debug(osc.conf.config)

append ``obs=<apiurl-hostname>`` to the **private** key's comment.
This will also work nicely during SSH agent forwarding, because the comments get forwarded too.

Disable hdrmd5 checks of downloaded and cached packages in ``osc build``.
It is recommended to keep the check enabled.
OBS builds the noarch packages once per binary arch.
Such noarch packages are supposed to be nearly identical across all build arches,
any discrepancy in the payload and dependencies is considered a packaging bug.
But to guarantee that the local builds work identically to builds in OBS,
using the arch-specific copy of the noarch package is required.
Unfortunatelly only one of the noarch packages gets distributed
and can be downloaded from a local mirror.
All other noarch packages are available through the OBS API only.
Since there is currently no information about hdrmd5 checksums of published noarch packages,
we download them, verify hdrmd5 and re-download the package from OBS API on mismatch.
The same can also happen for architecture depend packages when someone is messing around
with the source history or the release number handling in a way that it is not increasing.
If you want to save some bandwidth and don't care about the exact rebuilds
you can turn this option on to disable hdrmd5 checks completely.
