-- SYNOPSIS -- perform the update of all outdated targets.
--
-- DESCRIPTION
-- This is where we traverse the make graph looking for targets that
-- are out of date, and we try to infer how to make them if we can.
-- The usual make macros are understood, as well as some new ones:
--
-- $$ - expands to $
-- $@ - full target name
-- $* - target name with no suffix, same as $(@:db)
-- or, the value of % in % meta rule recipes
-- $? - list of out of date prerequisites
-- $< - all prerequisites associated with rules line
-- $& - all prerequisites associated with target
-- $> - library name for target (if any)
-- $^ - out of date prerequisites taken from value of $<
-- {{ - expands to {
-- }} - expands to }
-- \# - expands to #
