R build status

The goal of urlchecker is to run the URL checks from R 4.1 in older versions of R and automatically update URLs as needed.

It also uses concurrent requests, so is generally much faster than the URL checks from the tools package.


# `url_check()` will check all URLs in a package, as is done by CRAN when
# submitting a package.

# `url_update()` will check all URLs in a package, then update any 301
# redirects automatically to their new location.
