The append filter simply appends some text to the end or the begining of a buffer. Although this functionality could be be reproduced through the use of regular expressions, this filter was still added for convenience and simplicity.
|toAppend||the string to be appended||Yes|
|atEnd||flag indicating where the append string should be appended (at the begining or the end)||No, defaults to false|
<append Append="hello there"/>Append the word 'goodbye' to the end of all buffers
<append Append="goodbye" atEnd="true"/>
