To update Polyglot or LPG if you've installed a previous version:

Follow the same general procedure as for updating SAFARI, but with reference to the respective Polyglot or LPG items.

To update IMP if you've installed a previous version:

Note:  Some of the screenshots used in these instructions are out of date in that they stilll refer to IMP as "SAFARI."  The name will be changed to protect the innocent; in the meantime, if you can pretend that SAFARI really means IMP, these instructions should still be good.

  1. From Eclipse, invoke "Help" => "Software Updates" => "Find and Install".
  2. In the dialog that shows up, select "Search for new features to install" and click "Next"
  3. Check the item for "IMP" in the update site list on the left and click "Finish"
  4. It may take several moments for Eclipse to contact the update site and determine what updates are available.
  5. If you are already have the latest, you will simply get a dialog saying something like "No updates for the currently installed features found".
If there are any updates beyond what you already have, you should get a dialog showing "IMP Language Tools", with children named "IMP", "IMP Runtime", "X10DT",  and "JikesPG IDE" (as the release is currently constituted).
  1. Click the checkboxes next to the new versions of the features you want to update and click "Next".
    1. Accept the license agreement and click "Finish"/"Next"
    2. Click "Install All"
    3. Click "Yes" when asked whether to restart Eclipse
