Hmmm... ok. Here are 4 questions:


1. What about the scenario where you are shipping dependancys in a lib
directory or something?

Would you just set a CLASSPATH variable as an AUTOCONF variable
which could be overridden by the user as part of calling configure?

(note: I know how variables and such like work in autoconf: I want to
know what *you* would like to do in this circumstance).


2. Do we have existing macros for doing jar file autodiscovery? Or
   are you suggesting you would write some more M4?

3. Do you think, in this instance, that we should install gnujaxp.jar
   if it doesn't already exist.

4. can you get automake to build install targets given the way you've
   set it up?
