I really hope for some feedback on this design draft.

I looked for existing C++ code to parse .desktop files, and found
libxdgutils/ in <URL: http://gitorious.org/xdg-autostart/ > which seem
to do most of what is needed.  The KDE libraries have lots of
dependencies that it is probably best to avoid.  Mentioning it here
for future reference.  The license seem to be BSD-like.
