# Make variables come in two flavors, immediate or deferred.
#
#   Variable definitions are parsed like this:
#
#        IMMEDIATE = DEFERRED
#    or
#        IMMEDIATE := IMMEDIATE
#
#   Rules are parsed this way:
#
#        IMMEDIATE : IMMEDIATE
#           DEFERRED
#
# So you can assign variables in any order if they're only to be used in
# actions, but if you use a variable in either the target or prerequisite of a
# rule, the rule will be constructed using only the top-down, immediate value.
#
# So we'll try to define all the variables first. Then the rules.
#

##############################################################################
