%description
Simplifies the creation of reproducible data science environments using
the 'Nix' package manager, as described in Dolstra (2006) <ISBN
90-393-4130-3>. The included `rix()` function generates a complete
description of the environment as a `default.nix` file, which can then be
built using 'Nix'. This results in project specific software environments
with pinned versions of R, packages, linked system dependencies, and other
tools. Additional helpers make it easy to run R code in 'Nix' software
environments for testing and production.
