Those curly bracket items are template variables, not really functions.
The code is responsible for replacing those variables with the appropriate
dynamic HTML output. So, for example, in header.thtml you see
{welcome_msg}. Well, in COM_siteHeader() you'll see a call to
set_var('welcome_msg', $someStringVariable). It's that code that actually
replaces what you see.
