well.... my file is "doxygen"ized. the open issues are the
CATCHDESTRUCTOR macro i use to convert exceptions in destructor to
warnings. this must be replaced by some boost conformant stuff. also i
store reference to the object, therefore some of your fancy traitstuff
must be used. the rest i think is easy. what steps are neccessary to put
this into boost? actually i have no time at all :) but maybe i could do
it anyway, since it should be easy.
