From Fedora Project Wiki
This template is transcluded by the main template for release validation test pages, which is substituted into the test pages for each compose at the time of creation. For example, at the time Fedora 21 Beta TC1 was released, it was substituted to create Test_Results:Fedora_21_Beta_TC1_Base. The mess of #ifeq's at the top displays the 'no longer current' admon box if appropriate - it has to cover the possibility that the 'current' compose may be either a nightly or a TC/RC, so it has to use a couple of nested #ifeq statements.
