Changes in version 0.0.0.9000                      

  - Added check_url(), check_urls(), and check_paths(), wrapping
    lychee-lib via extendr to check single URLs, vectors of URLs
    concurrently, and links discovered in files, directories, or glob
    patterns.
  - Added check_package() to scan an R package's DESCRIPTION, Rd files,
    NEWS, CITATION, and vignettes for URLs -- mirroring CRAN's own URL
    check -- and check each one found.
  - Added lychee_options() to configure retries, timeouts, redirects,
    excluded/included URL patterns, and other lychee-lib behaviour
    shared by check_url(), check_urls(), check_paths(), and
    check_package(). Options can also be read from a lychee.toml file in
    the working directory.
  - Added check_file(), check_folder(), and check_project() as
    convenience wrappers around check_paths(): check_file() validates a
    single file, check_folder() adds recursive and extensions options
    for scanning a directory, and check_project() recursively scans a
    whole project directory while skipping dependency and build-artifact
    directories (node_modules, renv, packrat, target, dist, build,
    vendor) as well as hidden directories.
  - Fixed a Windows-only crash (STATUS_STACK_BUFFER_OVERRUN) that hit
    the R process after a rambutan call had already completed and
    returned its result, caused by the aws-lc-rs TLS crypto backend's
    teardown at DLL/process exit. rambutan now installs rustls's ring
    provider before building its HTTP client, avoiding the crash.
