The file ftp://ftp.redhat.com/pub/redhat/updates/6.1-us/i386/README
incorrectly names the RPMs. It omits the "us" in the names of the mask
A note stating that the last line is *not* in error would be nice. It
looks like someone typoed and put communicator instead of navigator.
Fixed. Thanks for noticing (and noticing that the last line
*isn't* a typo. :) )
