Let's take the
Contacts module inside my Magento 1.7 installation.
$ pwd /var/www/vhosts/myproject/magento-22.214.171.124/app/code/core/Mage/Contacts
Contacts is the module, but is
Mage the package, or the vendor? Then what's
core? I'll heard them being described as 'code pools', but still not very clear.
And how does this relate to namespacing? (if it's relevant at all?)
