Adds or removes config options.

Config options are simple toggles that are stored in the cookie roxen-config. This ensures that they are persistent for that user, the same user will have the same config options even if he returns to the site another day. If cookies cannot be used, prestate variables are used instead.

Use <if config=...> to test for the presence of a config option. <aconf> works just like the <a href=...> container tag, but if no href attribute is specified, the current page is used.

Example

<aconf +foo>Add the option</aconf>
<br><aconf -foo>Remove the option</aconf>

<p><if config=foo>
The option is set.
</if>
<else>
The option is not set.
</else>

The option is not set.
