Fedora headers searcher is a tool that analyzes #include directives in C/C++ header/source files and tries to map them to a Fedora RPM package that provides such file. Feaders uses DNF and it's repoquery plugin to search entire repository for provided files. The current approach for the search is rather brute-force, that being said, there's a lot of space for improvement and the performance so far has not been great.
