GNU Dionysus

a local machine search engine for universal constants and parameters of scientific and engineering relevance.

Dionysus is a convenient system for quickly retrieving the values of mathematical constants used in science and engineering. Values can be searched using a simple command-line tool, choosing from three databases: universal constants, atomic numbers, and constants related to semiconductors.

This package is looking for volunteers that would like to contribute to the project.
