External Functions are defined
in a special text file with a .xt
extension which are then
included into your Xtscript:
The function file can be local or
anywhere on the web !
[...] = optional ... = your value
include [domain.com/]name
call [domain.com]@name[;
$firstvar=...; $morevars=... ;
$last_var=...]
external functions can also be
called from html (file must be
included in a Xtscript first)

or like this


<!--parser:xtscript-->

include examples/filename.xt ,
your_site.xtgem.com/filename.xt
