 There's the following two paragraphs, but as an example let's say you
want something like $release but for "myapp". The way you could do
this is ship a config. file called "/etc/yum/vars/myapp_release" with
"3" in it and then you can have your myapp.repo file look like:

[myapp]
name = Myapp. repo. for version $myapp_release
baseurl = http://example.com/myapp/$myapp_release/$basearch

...the filename (key) can be "anything", but the config. file
processor only looks for the Regexp "[$]\w+". The contents of the file
(value) can also be anything, but yum will only read the first line
(and then removes the \n) ... also yum doesn't do any escaping, so if
you make the contents of "myapp_release" "foo&bar" then the url part
is going to be wrong.
