They're not made to play well with standalone applications. The most similar concept that plays well with standard applications is libraries in the Racket "lib" directory. Having packages that supply timezone information install the timezone files to Racket's "lib" (in the same way that a package like "db-win32-x86_64" installs a library) might be a better approach in the long run. If I understand, these files would make more sense in a "share" directory than in the "lib" directory. If that distinction seems important, we could add a 'share mode to `define-runtime-path` that is similar to 'lib mode. I think your solution so far, which relies on compile-time checks, will not work right with packages that are distributed in "built" form. That creates a problem, in turn, for building a Racket distribution. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
