# $NetBSD: bsd.tools.mk,v 1.12 2005/04/28 17:37:06 jlam Exp $
#
# This Makefile fragment creates tools under ${TOOLS_DIR} that are
# found before similarly-named tools in the system path.
#
# There are two ways to generate the tool: either create a wrapper script
# or create a symlink:
#
# TOOLS_WRAP is a whitespace-separated list of tools for which a
# wrapper script is created.
#
# TOOLS_SYMLINK is a whitespace-separated list of tools for which a
# symlink is created.
#
# 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 is either
# derived from TOOLS_REAL_CMD.<tool> for symlinks, or placed in
# the "bin" directory for wrappers by default.
#
# 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
# are used only by tools listed in TOOLS_WRAP:
#
# TOOLS_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_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.
