+Bitmasks for efficient storing of boolean flags.

+## Alternatives
+
+You might prefer the [bitset](https://hackage.haskell.org/package/bitset) package, that uses a similar implementation to this library. The main difference between `bitset` and `bitmasks` is that, contrarily to `bitset`, `bitmasks` is intended to be imported non qualified.

 ## Usage
 
 Define your flags as an enumeration:
