# Short explanation of how gstep-make works: (hh)
#
# The
#   internal-all:: $(LIBRARY_NAME:=.all.library.variables)
# eg expands to:
#   internal-all ::
#     libobjc.all.library.variables libFoundation.all.library.variables
# that is,
#   $target.$operation.$type.variables
# for each target (word in the LIBRARY_NAME (list) variable)
#
# The %.variables is matched in rules.make which then invokes
# it's $target.build rule which does the actual work. The %.build
# rule is a pattern rule extracting the variable set matching for
# the appropriate target. Eg when
#   libobjc.build
# is invoked, $($*_C_FILES) expands to the value of the variable
# libobjc_C_FILES which in turn is mapped in the nested invocation
# of make to the the plain C_FILES variable. In this step also
# which_lib is invoked to determine to correct library bindings.
# In other words, each target is run in it's own make process which
# has an environment only containing the variable bindings for that
# target (eg all libobjc_C_FILES, but not libFoundation_C_FILES).
