This module provides functions that deals with formatting data with Content-Type ‘text/plain; format=flowed’ as described in RFC2646 http//www.rfc-editor.org/rfc/rfc2646.txt. In a nutshell, format=flowed text solves the problem in plain text files where it is not known which lines can be considered a logical paragraph, enabling lines to be automatically flowed wrapped and/or joined as appropriate when displaying.
In format=flowed, a soft newline is expressed as “ \n”, while hard newlines are expressed as “\n”. Soft newlines can be automatically deleted or inserted as appropriate when the text is reformatted.
