Invisibly returns NULL. The primary purpose of this function is its
side effect: opening the specified S3 folder in a browser.
Arguments
path
(optional) Path inside the S3 folder to open. Defaults to the
root level (path = "") of the project's S3 folder.
root
S3 path of the project root. This serves as the reference point
for all relative paths. When left as NULL, the root is automatically
derived from the cloudfs.s3 field of the project's DESCRIPTION file.
