Sorry for the multi post first of all . In http://plone.org/Members/runyaga/presentations/OSCOM/workshop/oscom.html it says "Exposing existing python libraries is trivial." and "Zope and CMF provide the services that Plone consumes. What does this mean for a developer? * any/all libraries (thousands) available to Python are usable by Plone" But there is no documentation anywhere saying how this can be done . for instance I go to the web and find a great charting library pychart or chartdirector. How can I add it so that it is available in python script. Please don't respond by saying use ZGDCHART because Ihave tried this also and cannot get it to install either. I would prefer to learn how to add a library to zope . it can't be that hard. I have searched(google and the mailing lists) and found that if I put the library in my plone\python\lib\site-packages directory but once I do that I am not sure how to reference the library classes from the python script . I have tried doing an import but I keep getting import of <package name> is unauthorised. Any suggestions or help or suggestions for other things to google would be most appreciative. Thanks in advance. ____________________________________________ Peter Millar
