+Changes URL remote points to. Sets first URL remote points to matching
+regex <oldurl> (first URL if no <oldurl> is given) to <newurl>. If
+<oldurl> doesn't match any URL, error occurs and nothing is changed.
++
+With '--push', push URLs are manipulated instead of fetch URLs.
++
+With '--add', instead of changing some URL, new URL is added.
++
+With '--delete', instead of changing some URL, all URLs matching

+error.

 'show'::
 
 Gives some information about the remote <name>.
