So we have three seperate jar files, right? Then we need a way to put 
those in the bootclasspath of the calling VM. The VM will need to figure 
out the location of the jar files to add to it's bootclasspath.

Let's say we have


as an API.

Maybe even a

API later for those among us who like building from CVS checkouts ;)

So basically, I'm thinking about two APIs (macros), one for JARs, and 
another for rebuilding GNU Crpyto from CVS. I'll concentrate in the 
first, as that one seems to be easier to do as a prototype, and with 
lessons from that one, it should be easier to build the other.

I have the following in mind:

--with-gnu-crypto should set USE_GNU_CRYPTO as an autoconf variable, and 
PATH_TO_GNU_CRYPTO_JARS. Then, we can use one to check if kaffe should 
use GNU crypto, and the other to adapth the bootclasspath in the kaffe 
driver script, kaffe.in.

The options/switches depend on the options/switches from the GNU crypto 
configure.in you want the projects utilising GNU Crypto to be able to 
change. If there are any of them that make sense once you've uild the 
JAR files, we should list a set of --enable-gnu-crypto-something 
switches to allow the VM to enable those features.

I've cc:ed the kaffe mailing list, as I assume kaffe will provide the 
testbed for this type of integration.

Wasn't Morgon Kanter working on that? [1] What happened to that effort?
