How to use rsync to download RFCs

[1] To get the list of modules available

type rsync rsync.rfc-editor.org::

This will return results as follows:

[2] To create a mirror using a module

Type rsync -avz --delete rsync.rfc-editor.org::Module-Name Target-Directory
For example: To create a mirror of the text versions of all the RFCs, i.e.,
in-notes/*.txt
in-notes/bcp/*.txt
in-notes/fyi/*.txt
in-notes/ien/*.txt
in-notes/std/*.txt

type rsync -avz --delete rsync.rfc-editor.org::rfcs-text-only my-rfc-mirror
(The --delete option is useful for removing local copies of files that have been deleted from the repository. This is helpful to remove expired Internet-Drafts.)
