Functions
Each Smarty tag either prints a
variable or invokes some sort
of function. Functions are processed and displayed by enclosing the
function and its
attributes
into delimiters like so: {funcname
attr1="val" attr2="val"}.
function syntax
{$name}!
{else}
Welcome, {$name}!
{/if}
{include file="footer.tpl"}

Both built-in functions
and custom functions
have the same syntax within templates.
Built-in functions are the
inner workings of Smarty, such as
{if},
{section} and
{strip}.
They cannot be modified.
Custom functions are additional
functions implemented via plugins.
They can be modified to your liking, or you can add new ones.
{html_options} and
{popup}
are examples of custom functions.
