packages into its development environment.
```bash
cd {Cuis-Stable|Cuis-Current}/{Cuis7-0|Cuis-Smalltalk-Dev}
./drgeo/startIDE.sh
```
A new image **drgeoIDE.image** is built in CuisImage and started. This
is the development environment for the Dr. Geo.
In the Workspace window, execute the statement `DrGeoSystem
beDevelopment`, it will set up the paths to the resources to test
appropriately the application.
Then, to open a Dr. Geo window, execute:
```smalltalk
