# mono (c#) support
#
# Feature:	mono
# Usage:	USES=mono:ARGS
# Valid ARGS:	nuget
#
# MAINTAINER=	mono@FreeBSD.org
#
# Arguments:
#
# build		Specifies that mono is only a build-time dependency.
#
# nuget		Specifies that the port uses nuget packages.
#
#		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.
#
# makenupkg	This target will create nupkg-${NAME} files based on the
# 		port's downloaded packages in ${NUGET_PACKAGEDIR}
#
# Variables overrideable by the port:
#
# NUGET_PACKAGEDIR	The directory in which the port expects the
#			nuget packages to be available
#			default: ${WRKSRC}/packages
#
# NUGET_LAYOUT		The directory layout of ${NUGET_PACKAGEDIR}:
# 				legacy:
# 					${NAME}
# 					${NAME}.${VERSION}
# 					${NAME.tl}/${VERSION}
# 				flat:
# 					${NAME}
# 					${NAME:tl}
# 				dotnet:
# 					${NAME:tl}/${VERSION}
# 			default: legacy
#
# NUGET_FEEDS		A list of nuget feed names
#			default: NUGET
#
# ${NAME}_URL:		The base URL for the feed ${NAME}
#			defaults:
#				NUGET_URL=https://www.nuget.org/api/v2/
#				${NAME}_URL=https://dotnet.myget.org/F/${NAME:tl:S/_/-/g}/api/v2/
#
# ${NAME}_FILE:		The file containing a list of nuget packages from
# 			feed ${NAME} in the format:
# 				${name}=${version}
# 			default: ${PKGDIR}/nupkg-${NAME:tl}
#
# ${NAME}_DEPENDS:	The list of nuget packages from feed ${NAME} in the
#			format:
#				${name}=${version}
#			defaults:
#				NUGET_DEPENDS=${PAKET_DEPENDS}
#
# PAKET_PACKAGEDIR	The directory in which the port expects the
# 			nuget packages (managed by paket) to be available
#
# PAKET_DEPENDS		The list of nuget packages from a nuget feed.  The
# 			version used needs to be resolved (unlike how paket
# 			works).  The format is:
# 				${name}=${version}
