# 5.13. end Filter

## Interface

The general syntax is:

      !block end
      ...
      !endblock

See Understanding Filter Interfaces, if necessary.

## Description

The end filter is used to add a section of SDF onto the end of the document. This is particularly useful in configuration files when you want to:

- load a "exit" configuration module
- provide defaults for variables not provided by authors within a document.

When several sections are added to the end using this macro, the sections are processed in a first-in-last-out order.

## Examples

    !block end
    Line:
    N[align=Center] END OF DOCUMENT
    !endblock
