Booleano is an interpreter of boolean expressions, a library to define and run filters available as text (e.g., in a natural language) or in Python code.
In order to handle text-based filters, Booleano ships with a fully-featured parser whose grammar is adaptive: Its properties can be overridden using simple configuration directives.
On the other hand, the library exposes a pythonic API for filters written in pure Python. These filters are particularly useful to build reusable conditions from objects provided by a third party library.
