TemplatePageAttributes.java
Log:
added patch by Gary Lawrence Murphy <[EMAIL PROTECTED]>
DESCRIPTION:
The following patch adds two META tags and LINK tag support to
TemplatePageAttributes.
The new META tags carry the metadata for page authorship and the
generator, and while we can all use more self-promotion through
the author tag, I strongly recommend people use the default of the
setGenerator() method.
PROMOTE TURBINE!
The default setGenerator will list this page as generated by
"Jakarta Turbine 2.1" -- if this is in your Default layout all
project pages will be tagged as a Turbine product. This allows
the project crew and potential users to search on this string and
get a sense of how widely Turbine is deployed.
NOTE: If any this already exists in Turbine, please ignore this
patch! Also, check the patch carefully as I am not yet set
up to thoroughly test mods to the core classes. Your
mileage may vary. Consult your physician if symptoms
persist.
The second feature of this _really_ needed patching: This is the
ability to add arbitrary "link" tags. Some of you won't know what
these are or how to use them, but these tags are _essential_ for
creating pages accessible to blind users or those with physical
disabilities that frustrate surving with a 2D point/click cursor.
In a nutshell, using link tags lets handicapped visitors jump
quickly to the guts of your pages, for example
<link rel="NEXT" title="QuickStart" href="#mainpage"/>
<link rel="INDEX" title="FastTrack" href="#toc"/>
<link rel="HOME" title="FrontPage" href="http://www.teledyn.com/"/>
sets up three links right at the start of what they see/hear and
lets them get around the page without having to muddle through
your front matter.

Foundation to do with as they please.
