Hi Jan, I have attempted to build the sphinx documentation using dox.sphinx/build_docs.sh, and this appears to have run successfully and produced some html which shows the table of contents etc. However, I can't seem to find the documentation for any of the significant modules, e.g. cctbx/xray/structure.py. When I navigate to the link for the structure module within the xray package (dox.sphinx/_build/html/cctbx/cctbx.xray.html#structure-module), I see nothing other than a list of all the modules within the xray package. Am I missing something here? As a novice to using sphinx, I don't like to add significant documentation in sphinx style without being able to check via generating the documentation that what I have written is correct sphinx-speak. Cheers, Richard
