foo  = "bar"
bar  = $(foo) foo  # dynamic (renewing) assignment
foo := "boo"       # one time assignment, $(bar) now is "boo foo"
foo ?= /usr/local  # safe assignment, $(foo) and $(bar) still the same
bar += world       # append, "boo foo world"
foo != echo fooo   # exec shell command and assign to foo

#Magic variables
out.o: src.c src.h
  $@   # "out.o" (target)
  $<   # "src.c" (first prerequisite)
  $^   # "src.c src.h" (all prerequisites)

%.o: %.c
  $*   # the 'stem' with which an implicit rule matches ("foo" in "foo.c")
