>>> To ensure compatibility with other plugins, place this one at the
bottom of your list!

If you are using CGMV_Encyclopedia you also need to install the VE_ControlText
plugin!

=============================================================================
 ■ Usage
=============================================================================
Inside a description or message box, you can put any JavaScript Code
between ${}. It will replace that later with the result of your entered
JavaScript code.

a - references the current selected actor
p - game party
s - game switches
v - game variables
p - game party
item , skill - refers to the actual item or skill you are in.
(If you are inside the description box of skill or item)

>>> It can be possible, that it will not show the correct result. This can
especially happen on custom scenes. This will need a compatibilty fix then.

>> If you would like  to use an "if-else" inside the code block, you need
to use the "?" operator:

if (something) {
*   stuff
} else {
*   other stuff
}

is the same as

something ? stuff : other stuff
