Several people mentioned in #467 that they were seeing their C++ projects erroneously showing up as containing Objective C. I've added a file from each of the problematic repositories: - https://github.com/mp13on11/dwarf_mine - https://github.com/miguelishawt/anax - https://github.com/mholt/cppcsv - https://github.com/coder543/libcanister They all seem to be triggering on different aspects, since adding one sample wasn't sufficient to correctly classify the others. The discussion in #467 makes me think that perhaps Linuist might need to take the rest of the repository into account when classifying ambiguous files.
