# * pre/do/post-foo are always defined here, but empty. This is so
#   that we can call it (BSD make has .if target(foo) but GNU not)
#   and it won't error out.
# * ${_foo_COOKIE} are the actual targets
# * default is "auto" 
# * define "manual" if you need your own method
#   -> define a do-foo: target in the Makefile
# * if you have a style -> define a pre-foo: and post-foo: if they
#   are required, but the do-foo: magic is done here
