The prrd package was introduced recently, and made it to CRAN shortly thereafter. The idea of prrd is simple, and described in some more detail on its webpage and its GitHub repo. Reverse dependency checks are an important part of package development and is easily done in a (serial) loop. But these checks are also generally embarassingly parallel as there is no or little interdependency between them (besides maybe shared build depedencies). See the following screenshot (running six parallel workers, arranged in split byobu session).
This note announce the second, and much improved, release. The package now runs on all operating systems supported by R and no longer has external system requirements. Several functions were improved, two new helper functions were added in a so-far still preliminary form, and everything is more robust now.
The release is summarised in the NEWS entry:
