[armedbear-devel] Loading Lisp from JAR files committed to trunk

My work on [loading Lisp from JAR files has been committed to trunk][1].

With this modification, you may now package up the results of 
COMPILE-FILE (the packed FASLs ending in '.abcl') in a JAR file for 
loading with ABCL.

For example,

	(load "jar:file:///PATH/TO/the.jar!/foo")

would load the forms contained in "foo.abcl" packaged in the 
"/PATH/TO/the.jar" (relative paths for the 'file:' URI work as well).

Test code has been included, but currently only works under UNIX due to 
needing to pack the JAR file for testing via an external script.

Further things that should be eventually be addressed (by me, I presume):

1)  The Load.load() function could use some re-factoring.  This has 
proved to be rather difficult (or maybe I am just not thinking correctly 
in Java anymore), as my refactorings keep turning out longer and *more* 
convoluted than what is present.  I wanted to get the functionality out 
there with some tests as it seems the community (i.e. Alan) would like 
to use this sooner rather than later.

2)  Load from JARs not on local filesystem 

3)  Test what the *load-truename* variable gets bound to a little more 

"A screaming comes across the sky.  It has happened before, but there
is nothing to compare to it now."
