!! Variable evaluation order
The variables are evaluated in the following order:
# 'Preset' variables (or constants), as those listed on this page.
# 'Context' variables, as those set by plugins and tags.
# 'Property' variables, like those set in jspwiki.properties.
# 'Page' variables, like those set using the "SET" directive.
%% \\
!!! Overview
[{$pagename}] are variables that are evaluated when a page is viewed.
The two types of [{$pagename}] are defined below.!! Page Variables
Starting with JSPWiki 2.2, you can use the "SET" directive to define a variable that exists only in the page.
\\
You can access this value anywhere __on your page__ by using the shorthand "[[{$foo}]".\\
_%%information
Page Variables are effective when set in anyplace on the page regardless of the order. Setting a Page Variables at the bottom of the page implies it will work anyplace on the page.
%%
Accessing Page [{$pagename}] "[[{$test}]" before it is set:\\
test = [{$test}]\\
Then setting 'foo' to 'bar' For [example]:
\\
{{{
[{SET foo='bar'}]
}}}
creates you a variable called "foo", which has the value of "bar".
[{SET foo='bar'}]
Accessing "[[{$foo}]" After it is set:\\
foo = [{$foo}] \\

! Inserting JSPWiki properties
You can also access some of the [JSPWiki properties] (that have been defined by the site maintainer) by using their property names directly. See [SystemInfo] for an example.
Note that some properties might not be accessible due to security reasons.
You can also obtain some data from the [JSPWiki Plugins].
Needs more info on how to set global variables in jspwiki.properties. I cannot find how anywhere..
