+" DoxyGen syntax hilighting extension for c/c++/idl/java
+" Language:     doxygen on top of c, cpp, idl, java
+" Maintainer:   Michael Geddes <michaelrgeddes@optushome.com.au>
+" Author:       Michael Geddes
+" Last Change:  12 December 2005
+" Version:      1.15
+"
+" Copyright 2004 Michael Geddes
+" Please feel free to use, modify & distribute all or part of this script,
+" providing this copyright message remains.
+" I would appreciate being acknowledged in any derived scripts, and would
+" appreciate and welcome any updates, modifications or suggestions.
+
+" NOTE:  Comments welcome!
+"
+" There are two variables that control the syntax hilighting produced by this
+" script:
+" doxygen_enhanced_colour  - Use the (non-standard) original colours designed for this hilighting.
+" doxygen_my_rendering     - Disable the HTML bold/italic/underline rendering.
+"
+" A brief description without '.' or '!' will cause the end comment
+" character to be marked as an error.  You can define the colour of this using
+" the highlight doxygenErrorComment.
+" A \link without an \endlink will cause an error hilight on the end-comment.
+" This is defined by doxygenLinkError
+"
+" The variable g:doxygen_codeword_font can be set to the guifont for marking \c
+" words - a 'typewriter' like font normally. Spaces must be escaped.  It can
+" also be set to any hilight attribute. Alternatively, a hilight for doxygenCodeWord
+" can be used to override it.
+"
+" By default, hilighting is done assumng you have the JAVADOC_AUTOBRIEF
+" setting tunred on in your Doxygen configuration.  If you don't, you
+" can set the variable g:doxygen_javadoc_autobrief to 0 to have the
+" hilighting more accurately reflect the way Doxygen will interpret your
+" comments.
+"
+" Special thanks to:  Wu Yongwei, Toby Allsopp
