#
# gitlab.com master site handling
#
# To use, set in Makefile:
#
# DISTNAME=	exampleproject-1.2
# MASTER_SITES=	${MASTER_SITE_GITLAB:=accountname/}
#
# The following variables alter gitlab.mk behavior:
#
# GITLAB_PROJECT	defaults to PKGBASE
# GITLAB_TAG		defaults to PKGVERSION_NOREV
#			sometimes you want to override with v${PKGVERSION_NOREV}
#			SHA-1 commit ids are also acceptable
# GITLAB_RELEASE	defaults to not defined, set this to ${DISTNAME}
#			when packaging a release not based on a git tag.
# GITLAB_SUBMODULES	manually set submodule information:
#			values should be:
#			GitLab_user GitLab_project tag_or_hash submodule_path
# GITLAB_TYPE		overrides the autodetected MASTER_SITE URL scheme:
#
# "tag"
# This is the default when GITLAB_RELEASE is not defined. Example URL:
# https://gitlab.com/acct/${GITLAB_PROJECT}/-/archive/${GITLAB_TAG}/${GITLAB_PROJECT}-${GITLAB_TAG}.tar.gz
#
# "release"
# This is the default when GITLAB_RELEASE is set. Example URL:
# https://gitlab.com/acct/${GITLAB_PROJECT}/-/archive/${GITLAB_RELEASE}/${DISTNAME}.tar.gz
#
# Keywords: gitlab
