To install the patches for the CleanIO library:

1. from the clean folder delete the folders 'OsIO' and 'CleanIO'.
2. from the 'lib' folder in the clean folder delete the file
   'os2interface.lib'.
3. move the folders 'OsIO' and 'CleanIO' in the 'CleanIOPatch' folder
   to the clean folder.
4. move the file 'os2interface.lib' in the 'CleanIOPatch' folder into
   the 'lib' folder in the clean folder.

The compiler will compile the new files in CleanIO the first time
a clean program imports these modules.
