apply set operations like intersection to text inputs


setop is a simple console utility for handling multiple inputs from files or other streams as mathematical sets. That is you can apply typical set operations like union, intersection, or set difference and print a resulting set (sorted and with unique string elements) to standard output or you can give answer to special queries like number of elements.

Besides the default line-based parsing there are several options for choosing input sets and identifying set elements, and there are also several options for the type of output, e. g. it is possible to check for set equality or to check if one set is a subset of another.
