The full version of the Regina calculation engine that wrote this data file.

If a newer version of Regina exports to an older Regina file format, then the engine attribute will reflect the newer version of Regina that actually wrote the file.

If this file was created by hand or by an external program, the engine attribute should reflect this (it might contain the name and version of the external program, for instance).
