 [[Evan Lloyd]] I'm not sure if Outlook has mangled something, or I'm being obtuse,
but I'm not sure I follow the distinction you are making there.
However, if your objection is to the leading '*' then we can remove it.
By the way - shouldn't it be:
/**  Brief description

  Details
**/  (see Horor vacuii)

I actually think the CCS is woefully inconsistent in its example comment style, and that although leading '*'s are acceptable to Doxygen, it would be better to stick to one style (that of the file header comment, without leading '*'s) throughout.
