Local Copy of Repository

[das]

Hello Friends

I want to keep a local copy of the Fedora 7 repository, only the i386
branch. This will be updated in regular intervals, that I can break it
into DVD-s (or, even CD-s) and write them, and after installing F7 in a
machine, the 'yum' can be run on these DVD-s. 

We run a kind of a local Linux club (GLT Madhyamgram) and some of us
don't have Internet Connection at all, or, a dial-up connection. So, for
all these friends, and me too, because the Net connection is not always
very good (this is a third world version of broadband) and so it takes
quite a lot of time for 'yum' to initialize after checking the mirrors.
Running 'yum' on a locally updated repository will save this time. 

Now, can anyone please suggest a very simple way of doing this thing?
Remember I am no developer, just a teacher-writer involved in Linux. So,
something that I can work myself. For Ubuntu that thing is really there,
very simple instructions and that do work pretty well depending on
'debmirror' and 'debcopy'. I have done that myself, for our friends that
are using Ubuntu, and me too, before migrating to F7 due to Bangla
rendering problems in Ubuntu 7.04.
