+# @ECLASS: obs-download.eclass
+# @MAINTAINER:
+# miska@gentoo.org
+# @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.
+
+# @ECLASS-VARIABLE: OPENSUSE_RELEASE
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# From which stable openSUSE realease to take files.
+
+# @ECLASS-VARIABLE: OBS_PROJECT
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# In which obs project pakage is. This variable don't have to be set, if
+# OPENSUSE_RELEASE is provided.
+
+# @ECLASS-VARIABLE: OBS_PACKAGE
+# @REQUIRED
+# @DESCRIPTION:
+# Name of the package we want to take files from.
