# A Makeconfig file might contain a line like the following ones:
# FIRST   = f2mtz/
# LAST    = summary/
# EXCLUDE = extra/
# IGNORED_DIRS = no-go/ 
#
# The directory names specified in variables FIRST, LAST, EXCLUDE and
# IGNORED_DIRS *must* have a trailing slash to be compatible with
# directory names produced by the GNU Make $(dir ...) function.
#
# The EXTRA_TARGETS allows to specify which extra targets are understood
# by subdirectory Makefiles:
#
# EXTRA_TARGETS = configure install test
#
# The recursive Makefile will first descend to directories mentioned
# in ${FIRST}, and then into all the rest alphabetically. After that,
# the ${LAST} subdirectories will be processed.
#
# Directories mentioned in ${EXCLUDE} will be excluded from the
# automatic search, but can be included as FIRST or LAST members.
#
# Directories listed in ${IGNORED_DIRS} will be skipped even if they
# are listed in ${FIRST} or ${LAST}:
