# This Makefile fragment is included separately by bsd.pkg.mk and
# defines some variables which must be defined earlier than where
# bsd.extract.mk is included.
#
# The following variables may be set by the package Makefile and
# specify how extraction happens:
#
#    EXTRACT_ONLY is a list of distfiles relative to ${_DISTDIR} to
#	extract and defaults to ${DISTFILES}.
#
#    EXTRACT_SUFX is the suffix for the default distfile to be
#       extracted.  The default suffix is ".tar.gz".
#

_VARGROUPS+=		extract
_PKG_VARS.extract=	EXTRACT_DIR EXTRACT_ONLY EXTRACT_SUFX EXTRACT_CMD \
			EXTRACT_OPTS EXTRACT_USING EXTRACT_ELEMENTS
_SYS_VARS.extract=	EXTRACT_CMD_DEFAULT

EXTRACT_ONLY?=		${DISTFILES}
EXTRACT_SUFX?=		.tar.gz
