Remove the \file directive, as it is always superfluous because the current file is implicit [1]: > If the file name is omitted (i.e. the line after \file is left blank) > then the documentation block that contains the \file command will belong > to the file it is located in. Author names and e-mails are not relevant for us: it can always be inferred from git blame, and is often outdated. Eurecom code has been contributed and was under OAI PL v1.0/v1.1. For the cpack package contact: put generic email address that is independent of an individual and that will remain reachable. [1] https://www.doxygen.nl/manual/commands.html#cmdfile
