**ccn_rule_test**,
a FORTRAN90 code which
calls ccn_rule(), which
generates a quadrature rule based on a nested set of points
inspired by the Clenshaw Curtis quadrature rule.

ccn_rule, a FORTRAN90 code which defines one of a set of Clenshaw Curtis Nested (CCN) quadrature rules of any order.

- ccn_rule_test.sh, runs all the tests.
- ccn_rule_test.txt, the output file.

**CCN_09** is a nested Clenshaw Curtis rule of order 9,
which will exactly match the standard Clenshaw Curtis rule.

- ccn_o9_r.txt, the region file.
- ccn_o9_w.txt, the weight file.
- ccn_o9_x.txt, the abscissa file.
