# @BLURB: Reduces code duplication in the downloading from obs.
# @DESCRIPTION:
# This eclass constructs OBS_URI based on provided project in openSUSE Build
# Service and package name. It can be used later by packages/eclasses to
# download actual files.

# All you need to do in order to use it is set OBS_PROJECT and OBS_PACKAGE and
# inherit this eclass. It will provide OBS_URI in return which you will prepend
# to your files and use in SRC_URI. Alternatively you can just set
# OPENSUSE_RELEASE and OBS_PACKAGE and it will give you back OBS_URI for
# downloading files from obs projects corresponding to the specified openSUSE
# release.

# @ECLASS-VARIABLE: OPENSUSE_RELEASE
# @DEFAULT_UNSET
# @DESCRIPTION:
# From which stable openSUSE realease to take files.

# @ECLASS-VARIABLE: OBS_PROJECT
# @DEFAULT_UNSET
