What does $releasever and $basearch mean here?

Question

[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
enabled=1

And when will enabled=0 be useful? Why is there such an option?

They are both just yum variables which are automatically completed for you.

Enable = 0 will preventing you to use this repository.

	I still don't know how's `$releasever` assigned ... – yum Mar 15 '11 at 9:23
	If i'm not mistaken it derives the $releasever value from the version number of the package configured as "distroverpkg" (actually, whatever "provides" that in RPM parlance) in /etc/yum.conf, and $basearch from a call to the operating system's uname(2) function. – Bart De Vos Mar 15 '11 at 9:29
	@TiZon you are right. – Sacx Mar 15 '11 at 9:38
	'enabled' is useful is you want to do a one-off install of a package, but not use this repository for anything else. – Coops Mar 15 '11 at 11:06
