I’ve been experimenting with the T3 Framework and the Purity II and JA Blank templates. I noticed that the JA Purity II template had three files in the blocks directory…head.php, footer.php, and mainnav.php. The JA Blank template has nothing in the blocks directory, but still calls mainnav and footer blocks in the default layout. I’m assuming it’s using the block files in the JAT3 system plugin directory.
What is the purpose of the php files in the blocks directory of the Purity template? Are they overrides of the php block files found in the system T3 plugin blocks directory?
