# @BLURB: Simplifies downloading from openSUSE Build Service.
# @DESCRIPTION:
# This eclass constructs OBS_URI based on provided project in openSUSE Build
# Service and package name. It can be used 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 it 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 project corresponding to the specified openSUSE
# release.
