## Description

This represents a &snappea; triangulation packet, one of the many types of packet that together form the packet tree that a user sees when they open a ®ina; data file.

A &snappea; triangulation packet stores a 3-manifold triangulation using &snappea;'s own text-based file format (instead of ®ina;'s native format). This is useful when working with a triangulation that originated from &snappea; or &snappy;, since it will preserve all of &snappea;'s own internal data (e.g., peripheral curves and fillings).

The full contents of the &snappea; data file are contained in the character data that appears before the first child &xml; element. Whitespace and line breaks are relevant and are considered a part of the data file.
