# LIB is the first target of the makefile. This branch is executed 
# if no other name 
# is given in the calling command line. 
# the value of LIB is defined in MAKEFLAGS ; in the makefile syntax
# a line AAA=string defines the "MACRO" AAA 
# $LIB is then replaced by "string" ( i.e. $(FTOP)/libflukahp.a)
#
#  The target LIB is updated if
# it is older than its dependent(s) that is the name(s) following the
# semicolon. If the dependant has in turn #dependencies, theese are
# evaluated first, then the TABBED lines #below are executed. the $? means
# the list of dependents that are newer than the target : in our case all
# the .o files newer than libflukahp.a 
#   !!!!! beware : on OSFMI some objs were mis-timed as older than lib!!!
#               /usr/sbin/sync forces buffered
# files to be written on disk and their creation/modification date to be
# updated : to avoid desincronization on very fast machines
# a 1 second " sleep" time is added for safety

# here the rule to create the (SRCS:.f=.o)  target before using it as a depen
# dant for LIB 
# the definition (SRCS:.f=.o) is a "substitute sequence" way of defining
# a macro : in evaluating the value of SRCS, all the occurrences of .f
# are substituted by .o : this means in our case that the 
#"targets" to be updated ( or made if non-existant) are the object files. Their
# dependent is a file named "update" in the include subdir that is created and 
#"touch"-ed every time a modified include module is detected, by the 
# splitadd script.
# The rule itself is not given, it is implicitly 
# "inferred" as  the .f.o  rule ,since we are asking for a compiled file (.o)
# and the system expects that some source will be compiled
# ( this happens with a lot of canonical SUFFIXES )
