-##  SOURCE BLOCK FORMAT CLASS
-##
-##  A simple class containing compiled regular expressions to detect

-##  The `column' pattern must contain a group to `unbox' the content of
-##  documentation comment blocks.
-##
-##  Later on, paragraphs are converted to long lines, which simplifies the
-##  regular expressions that act upon the text.
