26 See `udkapi/com/sun/star/bridge/oleautomation/ApplicationRegistration.idl`
28 This is initialized in `Desktop::Main()` in `Desktop::OpenClients_Impl()`
29 by creating the service `com.sun.star.bridge.OleApplicationRegistration`,
30 which is implemented by `OleServer_Impl`.
32 See `extensions/source/ole/`
36 This allows embedding LO into a Win32 application as an ActiveX control.

42 On macOS, this allows indexing ODF documents with Spotlight.
44 See `extensions/source/macosx/spotlight/`
48 You can scan from LibreOffice, using platform specific backends like TWAIN/SANE.
