Steven --
If I understand the changes that you are making,

I HAVE VERY STRONG OBJECTIONS !

I am working hard at setting up an improved build scheme which does not
follow the limited uses which you have considered.

It appears that I will no longer be able to set the object directory to the
desired location because it is neither directly related to the entire `cwd`
nor does it end in "obj".

In particular, I need to be able to parse the path

{PREFIX}/src/{BRANCH}/file.c
and put the resulting object in
{PERHAPS_ANOTHER_PREFIX}/obj/{BRANCH}/file.o

As I understand it, your scheme will not permit this.

I still recomend consideration of some scheme that passes a "rule template"
rather than using any set of fixed rules. Only the "default rule" needs to
be built-in".
