Unfortunately, you have both missed my point. I am fully in favor of
keeping APR's _ability_ to be bundled in projects like SVN, httpd, and
flood. Is that clear?

APR was being bundled in projects like SVN, httpd and flood long
before apr-config was invented. At the time, APR could not easily be
installed independently of these projects, therefore bundling was the
only feasible method for using APR. In more recent times it was realized
that as we approach 1.0, we're going to need to give APR the ability
to be an independently installed library. In order to facilitate this,
apr-config was invented.

It seems to me that apr-config and apu-config have been abused to support
this older method of APR use. I strongly believe that by overcomplicating
these scripts, we will make it incredibly more difficult to use APR.
I also see no reason why bundling needs to be supported by these scripts
when it is already supported, and has been so for a very long time.
