This repository includes shared code used to read and rewrite R source and
binary package tarballs and ZIP archives without the overhead of temporary
files and multiple passes. It supports:
Reading and return DESCRIPTION information
Modifying the DESCRIPTION file
Extracting the package README
Calculating both the original and resulting tarball SHA256 hashes.
This library is used by Posit Package Manager to extract README/DESCRIPTION
data and rewrite packages internally for local and Git sources. It is also used
by the Posit Package Service when creating CRAN and Bioconductor package
snapshots.
