388 # The doxygen target helper will build software documentation using

390 # builder used supports automatic dependency generation (dependencies
391 # are automatically generated from the parameters specified in the \a
392 # doxyfile), automatic target emitters (the exact targets created are
393 # found parsing the \a doxyfile) and lots of other features. See the
394 # Doxygen builder documentation
396 # If \a extra_sources are given, the generated documentation will
397 # depend on them. This can be used to build images or other
398 # supplementary files.
400 # The doxygen target helper extends the builder with additional
403 # \li Fix tagfiles by removing namespace entries. These entries only
404 # work for namespaces completely defined in a single module. As
405 # soon as another module (which references the tagfile) has it's
406 # own members in that namespace, the crosslinking will break.
407 # \li If \c DOXY_HTML_XSL is defined as a construction environment
408 # variable, preprocess all generated html files (if html files are
409 # generated) by the given XSLT stylesheet. Since the HTML
410 # generated by doxygen is broken, we first filter the code through
411 # HTML-\c tidy and filter out some error messages.
412 # \li If xml output is generated we create files \c bug.xmli and \c
413 # todo.xmli which contain all bugs and todo items specified in the
414 # sources. The format of these files is much more suited to
415 # postprocessing and is a more database like format as the doxygen
416 # generated files (which are more presentation oriented). if \c
417 # DOXY_XREF_TYPES is given, it will specify the cross reference
418 # types to support (defaults to \c bug and \c todo). See <a
