What used to be the desktop in StarOffice 5 - now the binary.
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.
