 		YAQL (Yet Another Query Language) is an embeddable and extensible query
 		language, that allows performing complex queries against arbitrary objects.
 		It has a vast and comprehensive standard library of frequently used
 		querying functions and can be extend even further with user-specified
 		functions. YAQL is written in python and is distributed via PyPI.
