# $NetBSD: bsd.tools.mk,v 1.21 2005/05/15 01:17:05 jlam Exp $
#
# This Makefile fragment creates tools under ${TOOLS_DIR} that are
# found before similarly-named tools in the system path.
#
# TOOLS_CREATE is a whitespace-separated list of tools for which a
# corresponding tool is created. Either a wrapper script or a
# symlink is created depending on the tool that is being
# overridden.
#
# The following variables specify the details of each <tool>:
#
# TOOLS_CMD.<tool> is the path to the tool under ${TOOLS_DIR}. This
# variable is optional, and if left unspecified it defaults to
# ${TOOLS_DIRS}/bin/<tool>.
#
# TOOLS_ALIASES.<tool> is a whitespace-separated list of names for
# which <tool> should also be created under ${TOOLS_DIR}.
#
# TOOLS_REAL_CMD.<tool> is the path to the actual command that is
# invoked when ${TOOLS_CMD.<tool>} is called. If <tool> should
# be a symlink, then this variable is required and should be a
# full path. If <tool> should be a wrapper, then this variable
# is required unless TOOLS_REAL_CMDLINE.<tool> is defined (see
# below).
#
# The following variables specify further details of each <tool> and
# if set, cause a wrapper script to be created.
#
# TOOLS_REAL_ARGS.<tool> additional arguments that are passed to the
# real command ahead of any command-line arguments. This variable
# is optional.
#
# TOOLS_REAL_CMDLINE.<tool> specifies the full command-line to invoke
# in the wrapper script when <tool> is called. This variable is
# optional, and if left unspecified, then this is built up from
# TOOLS_REAL_CMD.<tool> and TOOLS_REAL_ARGS.<tool> by default.
#
# The following variables provide shortcuts for creating certain classes
# of tools:
#
# TOOLS_NOOP is a list of tools that do nothing and return true.
#
# TOOLS_BROKEN is a list of tools that do nothing and return false.
#
# TOOLS_GNU_MISSING is a list of tools for which the GNU missing
# script is invoked in place of the real tool. This is used
# primarily to hide GNU auto* tools.
