%description
A single key function, 'Require' that makes rerun-tolerant versions of
'install.packages' and `require` for CRAN packages, packages no longer on
CRAN (i.e., archived), specific versions of packages, and GitHub packages.
This approach is developed to create reproducible workflows that are
flexible and fast enough to use while in development stages, while able to
build snapshots once a stable package collection is found. As with other
functions in a reproducible workflow, this package emphasizes functions
that return the same result whether it is the first or subsequent times
running the function, with subsequent times being sufficiently fast that
they can be run every time without undue waiting burden on the user or
developer.
