# $NetBSD: bsd.pkg.extract.mk,v 1.16 2006/01/20 23:55:02 jlam Exp $
#
# This Makefile fragment is included to bsd.pkg.mk and defines the
# relevant variables and targets for the "extract" phase.
#
# 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_CMD is a shell command list that extracts the contents of
# an archive named by the shell variable "extract_file" based on
# the extension of the archive. The extensions understood by
# EXTRACT_CMD are listed in _EXTRACT_SUFFIXES.
#
# EXTRACT_CMD.<sufx> is a shell command list that extracts the
# contents of an archive named by the shell variable "extract_file"
# that ends in <sufx>.
#
# EXTRACT_USING specifies the tool used to extract tar/ustar-format
# archives. The possible values are "gtar", "nbtar", and "pax".
# By default, we use the "nbtar" tool (NetBSD's pax-as-tar).
#
# EXTRACT_ELEMENTS is a list of files within the distfile to extract.
# This variable only takes effect for distfiles that are tarballs.
# By default, this is empty, which causes all files within the
# tarball to be extracted.
#
# The following targets are defined by bsd.pkg.extract.mk:
#
# extract is the target that is invoked by the user to perform
# extraction.
#
# do-extract is the target that causes the actual extraction of
# the distfiles to occur during the "extract" phase. This target
# may be overridden in a package Makefile.
#
# {pre,post}-extract are the targets that are invoked before and after
# do-extract, and may be overridden in a package Makefile.
