1Chemistry::Ring version 0.19
2============================
3
4The Chemistry::Ring module provides some basic methods for representing a ring.
5A ring is a subclass of molecule, because it has atoms and bonds. Besides that,
6it has some useful geometric methods for finding the centroid and the ring
7plane, and methods for aromaticity detection.
8
9The Chemistry::Ring::Find module implements a breadth-first ring finding
10algorithm, and it can find all rings that contain a given atom or bond, the
11Smallest Set of Smallest Rings (SSSR), or the "almost SSSR", which is an
12unambiguous set of rings for cases such as cubane.
