%description
Turns a curated set of package archives (.tar.gz, .zip) into one
meta-package in the style of the 'tidyverse', so that a group of
interdependent packages can be distributed and installed as a single unit.
The generated meta-package records the exact archive versions it was built
from and installs its components in dependency order, so that whoever
receives it does not have to work out which package to install first. The
component archives are copied into the generated meta-package, so it is
the only artifact that has to be distributed and no directory has to be
agreed on between machines. Resolves dependencies by building a graph with
topological ordering and cycle detection, classifies them as local or
external, and detects implicit dependencies by scanning source code.
Installation needs no repository access unless a component depends on a
package that only exists in one, which suits teams working behind
institutional firewalls. Generates the complete meta-package scaffold,
including installation helpers, vignettes and documentation.
