%description
A suite of tools for transforming an existing workflow into a
self-documenting pipeline with very minimal upfront costs. Segments of the
pipeline are specified in much the same way a 'Make' rule is, by declaring
an executable recipe (which might be an R script), along with the
corresponding targets and dependencies. When the entire pipeline is run
through, only those recipes that need to be executed will be. Meanwhile,
execution metadata is captured behind the scenes for later inspection.
