ldelim,rdelim functions
##ldelim and rdelim are used to output delimiters, that is, curly brackets "{" and "}".
The template engine always tries to interpret the content inside the curly braces,
so if curly braces need to be output,
Please use this method.
eg:
{ldelim}funcname{rdelim} is how functions look in Smarty!
Output:{funcname} is how functions look in Smarty!
