I was assuming that they would leave the conf where it was and add

(:include "/my/checkout/path/asdf.conf")

into one of his/her normal source registry .conf files.

The whole idea is not to have to do complicated monkeying around (as in
your example of messing with *default-pathname-defaults*).

That way, all the user needs to know is the location of the .conf file,
and all the provider of the repository has to know is the structure of
his repository.

I may not fully follow questions about this mechanism, because I think I
am working in a different style from others.

For lack of this :here mechanism, I have been sticking with the old
style manipulation of asdf:*central-registry*.  When I set up a source
repo, I provide people who check it out with a simple, one-sexp way of
configuring ASDF to use it.  This typically uses an ASD-FINDER library
of mine, which does directory tree search for .asd files in portable CL.
 Then, e.g., when I start up a lisp session typically the first thing I
do will be to execute a function like


These are all names of projects I'm working on currently, and the effect
of the command is to populate asdf:*central-registry* appropriately.

This is necessary because typically the source repositories for these
projects contain different versions of different libraries.  In order to
get consistency across developers, we use no libraries except those in
the source repo (well, with the exception of SBCL contribs sometimes,
and we handle that by standardizing on a revision of SBCL to use).  The
source repositories are often clogged with Java code, in addition to
lisp code, meaning that simply using one of Fare's :tree directives can
be painful.

Hope that clarifies,
