ADDTOHEAD

You can write %ADDTOHEAD{...}% in a topic or template. This variable accepts the following parameters:

• _DEFAULT optional, id of the head block. Used to generate a comment in the output HTML.
• text optional, text to use for the head block. Mutually exclusive with topic.
• topic optional, full Foswiki path name of a topic that contains the full text to use for the head block. Mutually exclusive with text. Example: topic="System.MyTopic".
• requires optional, comma-separated list of id's of other head blocks this one depends on.

%ADDTOHEAD% expands in-place to the empty string, unless there is an error in which case the variable expands to an error string.

Use %RENDERHEAD% to generate the sorted head tags.
