Is there a way to manually trigger Safari 5's extension update check?

When developing Safari extensions, I'd like to be able to manually trigger an update check to ensure that my update.plist is correctly formatted and accessible.开发者_C百科 Has anyone found a way to do this? I haven't even been able to determine the standard update check interval.

You can force an update check by:

1. Opening Safari's Preferences
2. Selecting the Extension's Preference Pane
3. Clicking the "Updates" list item along the left hand side.

This will force an update check of all extensions you have installed.
