##############################################################################
# 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.
#
##############################################################################
# Configuration variables come first.
#
# Our convention is that we only use := for variables that will never be
# changed or appended. They must be defined before being used anywhere.
