The eopl language is now racket-based rather than mzscheme-based. This
test-suite, which was originally distributed on the book's web-site has
been re-written in the new language. Changes include dropping all
drscheme-init.scm and top.scm files. Remaining files were renamed to
use the .rkt extension and edited to use the #lang syntax (instead of
modulue). Require and provide forms were changed to reflect racket's
syntax instead of mzscheme's (eg, only-in vs. only). Several
occurrences of one-armed ifs were changed to use when and unless. All
tests have been run successfully.
