[racket-dev] Any notion of ".jar" files for Racket?

One of the things I'm encountering on the Brown network file system,
is that the number of files loaded by DrRacket causes some strain on
their systems.  I checked with the admins here, and by their count,
opening up DrRacket or doing things with 'raco make' can open about a
thousand files at startup time.

The Java folks have a notion of ".jar" files that pack a collection of
class files into a single archive, but also make it possible to load
classes directly out of .jars without an intermediate unpacking stage.
 .plt archives can serve a role to pack files together.   Does Racket
have a mechanism for loading modules out of them without unpacking?
