Having to deprecate a part of #poser's API for the first time, I added support for the #deprecated attribute supported by #GCC and #clang and then found #Doxygen couldn't automatically use it.
I didn't want to document deprecation *twice*, so I came up with a little hackery, see screenshots.
It's not perfect, requiring to type the message in plain text as a macro argument forbids the usage of a comma But hey, it works!
