# This Makefile fragment handles "replacements" of system-supplied
# tools with pkgsrc versions.
#
# The replacement tools are placed under ${TOOLS_DIR} so that they
# appear earlier in the search path when invoked using the bare name
# of the tool.
#
# "TOOLS_TOOLS" variables, e.g. TOOLS_AWK, TOOLS_SED, etc. are set to
# the full paths to the real tools on the filesystem, and represent
# tools required by the package.
#
# "TOOLS_CMDLINE_TOOL" variables, e.g. TOOLS_CMDLINE_AWK,
# TOOLS_CMDLINE_SED, etc. are set to the full command lines (path and
# arguments) necessary to invoke the real tools on the filesystem
#
# "TOOL" variables, e.g. AWK, SED, etc. are set to the full command
# lines necessary to invoke the real tools on the filesystem, and
# represent the tools required by pkgsrc itself.
#
# The tools that could be replaced with pkgsrc counterparts (usually
# GNU versions of the tools) that are required by pkgsrc itself, i.e.
# in targets that are part of pkgsrc infrastructure or part of the
# package Makefile, or by the package itself, i.e. within the
# software's own build system, should be listed as:
#
#	USE_TOOLS+=	awk gmake lex sed
#
# If a package requires yacc to generate a parser, then the package
# Makefile should contain one of the following two lines:
#
#	USE_TOOLS+=	yacc	# any yacc will do
#	USE_TOOLS+=	bison	# requires bison-specific features
#
# Adding either "yacc" or "bison" to USE_TOOLS will cause a "yacc" tool
# to be generated that may be used as a yacc-replacement.
#
# By default, any dependencies on the pkgsrc tools are build dependencies,
# but this may be changed by adding a :run modifier to the tool name,
# e.g.:
#
#	USE_TOOLS+=	perl:run
#

# XXX Keep this hack here until the day that msgfmt and msgfmt-plurals
# XXX is handled directly by the tools framework.
