I have successfully installed doxygen with doxywizard via the Ubuntu Software Center as I can see in a terminal:
user@user-D3220-B1:~$ whereis doxywizard doxywizard: /usr/bin/doxywizard /usr/bin/X11/doxywizard /usr/share/man/man1/doxywizard.1.gz
Starting doxywizard from the terminal works fine, but if I type it in the Dash nothing is found. Instead it says:
Sorry, there is nothing that matches your search.
Why is that?
