 This means that Vim will search for the MzScheme DLL files only when needed.
 When you don't use the MzScheme interface you don't need them, thus you can
 use Vim without these DLL files.
+NOTE: Newer version of MzScheme (Racket) require earlier (trampolined)
+initialisation via scheme_main_setup.  So Vim always loads the MzScheme DLL at
+startup if possible.
 
 To use the MzScheme interface the MzScheme DLLs must be in your search path.
 In a console window type "path" to see what directories are used.

+if it doesn't exist), "r5rs" module for test and "raco ctool" command for
+building Vim.  If MzScheme did not have them, you can install them with
+MzScheme's raco command:
