+# LibreOffice Binary
+
+Code for the LibreOffice main binary (`soffice`) resides here. The `soffice_main`
+function for the `soffice` binary can be found here.
+
+
+## Stable Interface
+
+Some of the artifacts built here are part of a LibreOffice installation set's
+stable interface, which (programmatic) clients can depend on.  Among them are:
+
+### soffice
+
+In the `program` directory (`program/` on Linux and Windows, `Contents/MacOS/`
+on macOS).
+
+### unoinfo
+
+In the `program` directory (`program/` on Linux and Windows, `Contents/MacOS/`
+on macOS).
+
+When called with a sole argument of `c++`, it prints to stdout an absolute
+pathname denoting the directory where the public URE libraries are found.
+
+When called with a sole argument of `java`, it prints to stdout a marker
+character (either an ASCII '0' or '1') followed by a sequence of zero or more
+absolute pathnames denoting jars or directories that need to be included in a
+class loader's search locations.
+
+If the marker character is '0' (on Linux and macOS), the pathnames are
+encoded as bytes, and any two pathnames in the sequence are separated from each
+other by NUL bytes.
+
+If the marker character is '1' (on Windows), the pathnames are encoded as
+UTF-16-LE two-byte code units, and any two pathnames in the sequence are
+separated from each other by two-byte `NUL` code units.
+
+## Other Binaries
+
+### oosplash
+Splash screen for the LibreOffice `soffice` binary.
+
+
+## Extensions
+
+The directory `test/deployment` contains some extensions to be used for testing:
+
+* `test/deployment/crashextension`: C++ extension to make LibreOffice crash. Useful for testing Crashreporter.
+  * Build with `Extension_test-crashextension`.
+  * Extension can be found in `workdir/Extension/test-crashextension.oxt`
+* `test/deployment/passive`: C++, Java and Python extension samples with passive registration.
+  * Build with `make Extension_test-passive`.
+  * Extension can be found in `workdir/Extension/test-passive.oxt`
+* `test/deployment/active`: C++, Java and Python extension samples with active registration.
+  * Build with `make Extension_test-active`.
+  * Extension can be found in `workdir/Extension/test-active.oxt`
