I'm trying to use NaturalDocs to document a project and it's not generating any documentation (it is generating a set of directories and files, just no documentation).
$ naturaldocs -i iulib -o HTML temp -p temp-proj -r
Finding files and detecting changes...
Parsing 62 files...
Updating CSS file...
$ naturaldocs -h | head
Natural Docs, version Development Release 12-07-2007 (1.35 base)

NaturalDocs -i [input (source) directory] (-i [input (source) directory] ...) -o [output format] [output directory]
iulib is a source tree containing standard C++ code with standard C++ extensions (.cc, .h). NaturalDocs should generate reasonable output with its default settings for such input.
