# $FreeBSD$
#
# mono (c#) support
#
# Feature:	mono
# Usage:	USES=mono:ARGS
# Valid ARGS:	nuget
#
# MAINTAINER=	mono@FreeBSD.org
#
# Arguments:
#
# nuget		Specifies that the port uses nuget packages.  The
#		variables NUGET_DEPENDS needs to be set with the names,
#		versions and optionally the port origin of the nuget
#		packages in the format:
#			${name}=${version}(:${PKGORIGIN})
#
#		EXTRACT_ONLY is conditionally overridden to exclude all
#		files with a '.nupkg' extension.
#
# Targets:
#
# makenuget	This target will output the NUGET_DEPENDS based on the
#		port's packages.config file.
#
# Variables overrideable by the port:
#
# NUGET_PACKAGEDIR	The directory in which the port expects the
#			nuget packages to be available
#			default: ${WRKSRC}/packages
