CharRecog

Simple answer is to use Genie instead -- it is a full featured 
character recognizer, and it is integrated into the UI.

I wrote CharRecog in Feb 96 to test the first version of Squeak. It 
uses the classic Gabe Groner GRAIL recognizer at RAND in the 60s. The 
theory of these recognizers is that it is better to be quick and 
perfect and require a little user training than to be natural and 
make mistakes (Grafitti has the very same approach).

Genie is much more extensive and a very nice piece of work by 
Nathanial Scharli.

Cheers,

Alan
