html_

_head
  _title "title='Document'"

Meta Module

__meta command sets machine readable information. Its 'name' attribute defines the property name; 'content' attribute defines the property value; 'scheme' attribute interprets the property value; 'lang' attribute specifies the language; and 'http-equiv' attribute provides HTTP server information for response header.

__meta "name='author' content='David Robert' scheme='ISBN Author'"
__meta "http-equiv='Expires' content='Fri, 25 Dec 1998'" 

http-equiv may be used to wait seconds and refresh to another page. Following example waiting 2 seconds and switch to new URL in content.

__meta "http-equiv='refresh' content='2, http://www.neatware.com'" 

When the name's value is a keyword, it is helpful to list a series of keywords in the content's value for search engine readable.
