[plt-scheme] PLT Scheme v202 available

PLT Scheme v202 is now available from

  http://download.plt-scheme.org/

This maintenance release addresses certain issues with the 
previous v201 release.  Specifically, there are fixes 
for:

  - teachpack functions such as `convert-file' and 
     `guess-with-gui-list';

  - launching a Web browser to read Help files in DOS-based 
     versions of Windows (95/98/Me);

  - the "Quit" menu in Mac OS X; and

  - Help Desk and networking under Mac OS 8/9.

All users should strongly consider updating to this new 
version.

Enjoy!
