    I was slightly puzzled before by the


    which I've just changed, taking the statement out of the assert. Does this
    mean that plugins never unloaded in non-debug builds?

    Anyway, they should now. Also, the Spider is almost finished now.

    Document import/export poses a real challenge. The only API I've been
    considering for that is the simple convert unknown format to known format
    (TEXT, RTF, DOC, AWML, + maybe eventually [XP]HTML), i.e.

    extern "C" [...] int
    convert_document (const unsigned char * source_buffer,
                      unsigned long source_length,
                      const char * source_content_type,
                      unsigned char ** buffer,
                      unsigned long * length,
                      char ** content_type);

    If I understand you, the AbiCapi plugin is never explicitly registered
    as an AbiWord plugin?
