Greetings,

It has been well over a year since last time I mentioned this paper
"Recursive Make Considered Harmful",
(http://miller.emu.id.au/pmiller/books/rmch/). so I hope it is ok that I
do it again.

Nice little reading for those that find themselves wondering if they are
the only ones that think make is somewhat lacking, at times.
