Re: "non-local" components in asdf

Hi James,

I'm not an expert, but I'll take a stab. I think the right way is to 
push any directory that will have a .asd on to 
asdf:*central-registry. Then the system definition can reference 
other system definitions with a :depends-on specification. I have 
included an example below where clsql-postgresql-socket depends on 
two other systems clsql-base and uffi.

You still have to get the path of each .asd file in the registry 
somehow. But the nice thing is that once you have this systems can be 
moved around without breaking anything.

I'm glad to hear you are thinking about asdf for cl-xml. I found the 
loading it to be a bit confusing. It may also simplify things if you 
are doing integration with Portable AllegroServe since it also uses 
ASDF.

Best,

John DeSoi, Ph.D.
