# $NetBSD: bsd.extract-vars.mk,v 1.2 2006/06/06 15:28:52 jlam Exp $
#
# 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".
#
EXTRACT_ONLY?= ${DISTFILES}
EXTRACT_SUFX?= .tar.gz
###
### Discover which tools we need based on the file extensions of the
### distfiles.
