+* What Is This??? |
|
| 2 |
+ |
|
| 3 |
+An experiment with Lispworks CAPI to create a Lisp listener with a |
|
| 4 |
+space for dynamically created components: think a widget that runs |
|
| 5 |
+your tests and displays the results. The idea is to provide a |
|
| 6 |
+repl-like gui that can be adjusted as necessary to suit one's |
|
| 7 |
+immediate needs. |
