## Usage
A simple usage example:<br/>
```bash
-cgrep --func --var --regex n[aA]m ./cgrep.cpp
+cgrep -A 1 -B 1 --func --var --regex n[aA]m ./cgrep.cpp
```
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/>
