# @ECLASS: nuget.eclass
# @MAINTAINER: cynede@gentoo.org
# @BLURB: Common functionality for nuget apps
# @DESCRIPTION: my idea of nuget was following:
# introduce nuget IUSE flag for packages that are on nuget to download them from nuget. (if sources fails with some reason or dependies is complicated or if user just want binaries).
# or maybe even introduce few packages that just downloads and instulls from nuget, reason is obviously - easy maintaince

inherit nupkg
