At this time, the library is header-only for easy integration with projects.

## Creating a single header
|
||||
|
||||
For maximum ease of use, a script called `single.py` is provided. You can run this script to create a single file version of the library so you can only include that part of it. Check `single.py --help` for more info.
|
||||
|
||||
## Features
|
||||
|
||||
- Supports retrieval and setting of multiple types including `std::string`.
