It waits 25 seconds (so that it +does not interfere with the startup itself), and then calls +`UpdateCheck::initialize()` (from `extensions/source/update/check/updatecheck.cxx`). + +This creates one more thread, `UpdateCheckThread`, that regularly checks whether +we have reached the time when we should ask for the update. If yes, asks for +that, and shows the download button in the menu (if the new update is +available). + +## OLE Automation Bridge + +A bridge between "OLE automation" and UNO, so you can use UNO services +from JScript, VBScript, etc. + + + +See `udkapi/com/sun/star/bridge/oleautomation/ApplicationRegistration.idl` + +This is initialized in `Desktop::Main()` in `Desktop::OpenClients_Impl()` +by creating the service `com.sun.star.bridge.OleApplicationRegistration`, +which is implemented by `OleServer_Impl`. + +See `extensions/source/ole/` + +## ActiveX Control + +This allows embedding LO into a Win32 application as an ActiveX control. + +See `extensions/source/activex/` + +## Spotlight Provider + +On macOS, this allows indexing ODF documents with Spotlight. + +See `extensions/source/macosx/spotlight/` + +## Scanner Support + +You can scan from LibreOffice, using platform specific backends like TWAIN/SANE. + +See `extensions/source/scanner/` + -- cgit v1.2.3
