The bad guys in the star wars fantasies are children compared to the 
bad guys of human history or even of the imagination of the greatest of 
creative artists ( of which George Lucas doesn't even begin to qualify ).

Sorry, couldn't resist.

Everyone to their own opinion <g>.

Much boilerplate C++ code has been created in Boost libraries using the 
facilities of Boost PP. My won Boost VMD adds to that ability for those 
who are interested. C++ macros are like any other language facility, 
valuable if used correctly, poor if misused.

All CXXD does is just work ! I guess that must be evil.

I do point out in the doc potential problems using a macro-based 
solution. But I found it the easiest way to achieve what I wanted to do 
with the least amount of work on the end-user's part, so I opt for it 
for myself. I only hope others will find it as useful.
