does fedoralegacy depend on fedora.us?

[Joe Pruett <joey clean q7 com>]

since there still isn't an official apt or yum for fedora legacy on rh9 
boxes, we are instructed to use the fedora.us version.  further, we are 
only instructed to add the fedoralegacy.org url to the sources.list file 
and not to comment out the fedora.us urls (or the macromedia ones in 
sources.list.d).  is this an oversight in the docs (like not telling us to 
install the fedora legacy key)?  or are you relying on the other rpms that 
fedora.us would install (10 packages that i see via apt-get -s upgrade)?  
i have assumed this is an oversight and not installed the fedora.us rpms, 
but clarification would be good, as well as updating the docs.
