Ability to load ASDF systems off JAR files in the classpath

I'd really like the ability to pop an
asdf central registry directory into the abcl jar and have abcl be
able to asdf load from there. Would really simplify packaging apps
based on abcl.

More or less working with ASDF2 and jar Pathnames.

Marking as part of 0.21.

Whoops, we're at 0.20.

ASDF loading from jar files now works, but Alan is asking for a bit more packaging as well. I think a solution is quite reachable with ASDF2, but I don't have enough time to test it for the 0.20 release, so I am pushing this to 0.21 after all.

[Mark Evenson]

I think this exists, as of abcl-0.20, Pathnames are fully capable of referring to JAR files via the 'jar:' IRI scheme (works for 'jar:file', 'jar:http').

Loading ASDF definitions from JAR files has been possible since 0.21. For an example, see the abcl-contrib jar created in the build system, which is packaged as a JAR file.
