12# Make variables come in two flavors, immediate or deferred.
13#
14# Variable definitions are parsed like this:
15#
16# IMMEDIATE = DEFERRED
17# or
18# IMMEDIATE := IMMEDIATE
19#
20# Rules are parsed this way:
21#
22# IMMEDIATE : IMMEDIATE
23# DEFERRED
24#
25# So you can assign variables in any order if they're only to be used in
26# actions, but if you use a variable in either the target or prerequisite of a
27# rule, the rule will be constructed using only the top-down, immediate value.
28#
29# So we'll try to define all the variables first. Then the rules.
30#
31
32##############################################################################
33# Configuration variables come first.
34#
35# Our convention is that we only use := for variables that will never be
36# changed or appended. They must be defined before being used anywhere.
