template wiki:
[emplate is some form of device to provide a separation of form or structure from content.In publishing for example, a template may be a predefined layout to give you an idea what to write where with boxes and lines; a single-page newsletter template (for instance), might have a few columns, space for a picture and gaps for the headline and name of the newsletter.Templates can be used by humans or by automated systems; many web-based software packages now use a templating system to separate the logic of the program from the displayed formatting. Typically, these templates will include variables (often denoted {VARIABLE} ), and possibly a few logical operators to allow better adaptability of the template. Examples of template engines are Cheetah, Smarty and XSL Transformations.
