R help - Mar 2010 - Searching for option explanations

Hey all,

Sorry if this is redundant, but I can't figure out a good search query for
either the mailing list, or google, to find an answer to this.

Let's say I have a couple of R options I'm interested in learning more
about, but their details aren't explained in the command's help file.
For example, for R CMD BATCH --help, it discusses the use of --restore, --save
and --no-readline. But there are no in depth details about those options
themselves.

If I wanted to learn more about what --no-readline is, or --restore or --save,
is there some basic R resource I can use to find this? I tried exploring
options(), but I don't necessarily see what I'm looking for there. And
google searching "R '--restore'" is not providing much of 
value in return. Am I missing something obvious on how to do this?

Any thoughts would be greatly appreciated. Thanks for your help!

What you are asking about is startup options, right?
