# Configuration for make itself:

# Warn if the Makefile references undefined variables and remove built-in rules:
MAKEFLAGS += --output-sync --warn-undefined-variables --no-builtin-rules --no-builtin-variables

# Remove output of failed commands, to avoid confusing later runs of make:
.DELETE_ON_ERROR:

# Remove obsolete old-style default suffix rules:
.SUFFIXES:

# List of targets that don't represent files:
.PHONY: all clean

# =================================================================================================

# The PDF files to build, each should have a corresponding .tex file:

# The TXT files to build, each should have a corresponding RFCv3 XML file:

# Master build rule:
all: $(TOOLS) $(PDF_FILES) $(TXT_FILES)
