Creates a OpenOffice.org Add-On project.
A OpenOffice.org Add-On is an external UNO
component providing one or more functions through the user interface
of OpenOffice.org. A typical Add-On is available as a
UNO package for easier deployment with the pkgchk tool. In addition to
an ordinary UNO package, an Add-On package contains configuration
files which specify the user interface, registration for a protocol
schema, and first-time instantiation.
