Pseudo reproducible research

Some figures are ``hazardous'' or impossible to rebuild, although the mechanism for rebuilding is working perfectly. One reason could simply be that it takes too long to rebuild the figure or that you need specific hardware to run the programs or that a data set is missing. The author can put messages or explanations into the file NAME.warning. This will trigger the existence of a button which lets the reader display the warning message before burning figures or attempting to build them. If the warning is ignored and the button is pressed anyway, a menu will prompt him to really destroy that figure.
