%description
    Libfa allows you to perform certain operations on regular languages,
    not just regular expressions. For example, if you have to decide
    if two regular languages have words in common. Computations
    like these require working with finite automata, one of the
    theoretical underpinnings of regular expressions. Libfa is largely a
    reimplementation of Java's dk.brics.automaton in C.
