On the PLT Scheme side, you can set these pieces in one of two ways:

 * If you're using `mzc --gui-exe' to build the executable, and if the
   main module file is "prog.scm" then create

       - "prog.filetypes" (in the same directory) to provide
         file-type information, including icons for document types

       - "prog.icns" (in the same directory) for the application icon

   The details on these are currently in collects/launcher/doc.txt and
   collects/compiler/doc.txt.

 * If you're using the `create-embedding-executable' Scheme API, then
   this information is provided via the `aux' argument. You can build
   up that argument by using `build-aux-from-path', which uses the same
   pieces as `mzc --gui-exe'.
