PreferencesXml

Specifying computing preferences in XML

In addition to the various GUIs, you can set computing preferences by creating and editing an XML document.

To do so, create a file global_prefs_override.xml in your BOINC data directory, with the following structure. All elements are optional; if you omit them, the BOINC defaults will be used.
