Does UNO depend on OpenOffice.org?
In the near future, there will be an Office Development Kit available for download beside the openoffice.org-setup-set. This development kit contains all files (include-files, libraries, tools, etc.) that are necessary to build components. The development kit will also contain samples. These samples are built with makefiles, that only require gnumake (not the whole openoffice.org build environment). These makefiles can be used as a template to integrate the build of your UNO-components into your build environment.
