  Description     : Congruence subgroups of SL(2,Integers)

The Congruence  package provides functions to construct several types of
canonical congruence subgroups in SL_2(Z), and also intersections of a finite
number of such subgroups. Furthermore, it implements the algorithm for
generating Farey symbols for congruence subgroups and using them to produce a
system of independent generators for these subgroups

I am packaging this because it is suggested by gap-hap (see Bug#968545).
