It will add additional dependencies of asciidoc, docbook-xsl and/or
something to default perf install command.  I don't know it matters
much, but just wanted to say.  What if a user want to install the perf
but the required packages for documents are not installed?

Is this needed?  Shouldn't we fix perf --help handling?  Please see my
other post on the issue.

Thanks,
