 The "hello world" of Xtscript
 All syntax must be written in 
 <xt:code> blocks 
 and inside them into 
 <!--parser:xtscript--> 
# <!-- this is optional *
and 
# -->  this is optional *
<!--/parser:xtscript-->. 
 Each command  must  be on a new line. 
 Your XtScripts can be as large or as small as you need them to be.
* adding this stops the web templates highlighted text editor from parsing the contents as html and serves no other purpose
