2914,Support for cumulative parameters in a doxyfile,brian@…,René Rivera,"It would be nice if it was possible to specify cumulative parameters as arguments to <doxygen:param>. Aliases for instance really require this. E.g.:

{{{
DOXYGEN_PARAMS =

    ...

    ALIASES+=defModule{1}=""\""\module{\1} \defgroup group_class_\1 \1\""""
    ALIASES+=module{1}=""\""\ingroup group_class_\1 \\n<div><span class=\""module\"">Module:</span>&nbsp;&nbsp;<span class=\""module_text\"">\ref group_class_\1</span></div>\""""

    ...

    ;

doxygen doc.html
    :   [ glob include/*/*.hpp ] # or whatever
    :   <doxygen:param>$(DOXYGEN_PARAMS)
    ;
}}}

Currently the parser chokes on the += construct; it expects = always. I have tinkered with doxygen.jam in my local BBv2 dir, but I am very unsure about the correctness of what I'm doing. FWIW here is the patch for what I currently use...
