0003 # NEPOMUK_GENERATE_FROM_ONTOLOGY
0004 # Parameters:
0005 #   ontofile     - Path to the NRL ontology defining the resources to be generated.
0006 #   targetdir    - Folder to which the generated sources should be written.
0007 #   out_headers  - Variable which will be filled with the names of all generated headers.
0008 #   out_sources  - Variable which will be filled with the names of all generated sources.
0009 #   out_includes - Variable which will be filled with complete include statements of all
0010 #                  generated resource classes.
0011 #
0012 # In addition to the parameters an arbitrary number of template filenames can be set as arguments
0013 #
0014 # In case of success NEPOMUK_RESOURCES_GENERATED is true, otherwise false
