| <h2>Choosing plug-ins to run</h2> | |
| <p>It is possible to alter the list of plug-ins and fragments that PDE will pass | |
| to the run-time workbench when running or debugging. By default, <b>Plug-ins and | |
| Fragments</b> tab is configured to select all the workspace plug-ins and | |
| external plug-ins that are enabled in the Preferences. However, choosing another | |
| radio button shows the list of plug-ins that can be individually selected or | |
| deselected:</p> | |
| <p> In order to support tracing without the need to edit the tracing <b>.options</b> files, PDE provides a | |
| "Runtime Tracing" preference page that allows you to set the tracing flags | |
| and name filters related to loading.</p> | |
| <p align="left">Runtime class load tracing is treated specially since it is general | |
| and useful for most plug-in developers. PDE also provides a generic dialog for controlling | |
| other tracing flags. The Advanced Tracing preference page shows all of the plug-ins that support tracing. | |
| When a plug-in is selected, its supported tracing options are shown in the property | |
| sheet. You can change the values of these tracing options for workspace and | |
| external plug-ins.</p> | |
| <p align="left">If you add tracing support to the plug-in under development, | |
| these tracing values will show up in this page.</p> | |

| <p align="left">You can select workspace and external plug-ins individually or | |
| as a group. This gives you great flexibility, but with flexibility comes the | |
| danger of ending up with an invalid configuration. Use this feature carefully | |
| and press <b>Restore Defaults</b> when you are not sure what the original | |
| setting was.</p> | |
| <p align="left">If you want to know exactly where all the plug-ins you are | |
| passing to the run-time workbench are coming from, press <b>Plug-in Paths...</b> | |
| button. A window listing the URLs of all the plug-ins will open.</p> | |
