# $NetBSD: install.mk,v 1.80 2021/08/14 08:38:01 rillig Exp $
#
# This file provides the code for the "install" phase.
#
# Public targets:
#
# stage-install:
#	Installs the package files into LOCALBASE or ${DESTDIR}${LOCALBASE}.
#

# Interface for other infrastructure components:
#
# Hooks for use by the infrastructure:
#
# privileged-install-hook:
#	This hook is placed after the package has been installed,
#	before leaving the privileged mode.
#
# unprivileged-install-hook:
#	This hook is placed _before_ switching to privileged mode
#	in order to install the package.
#

# User-settable variables:
#
# INSTALL_UNSTRIPPED
#	If "yes", all binaries and shared libraries are installed
#	unstripped. Otherwise they are stripped while being installed.
#	This option is not supported by all packages.
#
# STRIP_DEBUG
#	If set to "yes", call ${STRIP} -g to remove debug information
#	from all files. The symbol tables are still preserved.
#
# Keywords: strip unstripped
#
# Package-settable variables:
#
# INSTALLATION_DIRS
#	A list of directories that should be created at the very
#	beginning of the install phase. These directories MUST either
#	be paths that contain a leading {PREFIX}/ or be relative
#	paths. As a convenience, a leading gnu/ is transformed to
#	${PKGGNUDIR} and a leading man/ is transformed to ${PKGMANDIR},
#	to save package authors from typing too much.
#
# AUTO_MKDIRS
# INSTALLATION_DIRS_FROM_PLIST
#	In most (or even all?) cases the PLIST files in the package
#	directory already contain all directories that are needed.
#	When this variable is set to "yes", all directories mentioned
#	in the PLIST files will be created like in INSTALLATION_DIRS.
#
# DESTDIR_VARNAME
#	A variable name that should be set as staged installation location
#	presented as ${DESTDIR} at install phase.
#	"DESTDIR" is set by default.
#
# STRIP_DEBUG_SUPPORTED
#	If set to anything other than "yes" (the default), stripping will
#	be disabled for the package.
#
# STRIP_FILES_SKIP
#	A list of files relative to ${PREFIX} that will not be stripped.
