The text-box recovery tool allows DrScheme v370 and later to read programs created using v360 and earlier that include test-case boxes.
When opened using this tool, test-case boxes are turned into check-expect forms.
Test boxes plain-text tests and expected results are converted to plain-text check-expect forms.
If either the test or expected-result expression contains non-text (e.g., an image), the converted form is a comment box containing a check-expect form. The box should be easy to remove using the Scheme|Uncomment menu item in DrScheme.
