[Libreoffice] LibreOffice / OpenOffice.org sniffing in extension

Hi,

I am involved in a project that develops a few extensions (mostly in Java)
for OpenOffice.org and LibreOffice, and I would like to find a way to make
an extension detect in which of these two office suites it is installed. I
have not been able to find this in API documentation or elsewhere. Can you
give me a hint?

(Background: each of the extensions work in both OOo and LibO, but two of
the extensions can't be used together in LibO 3.3.)

Best regards,

Christophe
