```
All functions (except the literal operator) are in the namespace `frob`.
## Configuring
By default we use the same mechanism as `memfrob()`: ROT13 via bitwise xor of the number 42.
If you would like to use a different number for the bitwise xor, defined the constant `FROB_CONSTANT` before `#include`ing the header.
``` c++
#define FROB_CONSTANT 82
#include "cfrob.hpp"
```
Note that the defined constant must fit in the range `0-255` inclusive.
# Test
Run `make test` to build and run the test that ensures the original string literal does not appear anywhere in the outputted binary.
