 Should be more or less fine for other C-family languages as well but I haven't tested for those since I don't use those. Let me know if you run into trouble using cgrep on those.<br/>
 The goal is to make the options and features as similar to `grep` as possible for ease of use.<br/>

 Pleade do note that the regex will pass through both C++ and the regex engine, so if you would want to escape `\`, the regex you pass as the commandline arg would be `\\\\` instead of the normal `\\`.<br/>
-In order for cgrep to work, you need to have a compilation database, tools like cmake can generate one for you.<br/>
-If your build tool doesn't do that, you can just use [bear](https://github.com/rizsotto/Bear).<br/>
