<emphasis>header</emphasis> is a function that passes a raw header
string to the output. If your template is used for WAP (Wireless
Access Protocol) for example, you would need to send a special
header to indicate the type of content you are sending.

TECHNICAL NOTE: Be sure you call {header ...}
<emphasis>before</emphasis> any output in your template, in
including whitespace. Otherwise the header will not work as
intended.
