Writer Implementations
----------------------

Three implementations of the writer object interface are provided as
examples by this module.  Most applications will need to derive new
writer classes from the `NullWriter' class.

`NullWriter()'
     A writer which only provides the interface definition; no actions
     are taken on any methods.  This should be the base class for all
     writers which do not need to inherit any implementation methods.

`AbstractWriter()'
     A writer which can be used in debugging formatters, but not much
     else.  Each method simply announces itself by printing its name and
     arguments on standard output.

`DumbWriter([file[, maxcol` = 72']])'
     Simple writer class which writes output on the file object passed
     in as FILE or, if FILE is omitted, on standard output.  The output
     is simply word-wrapped to the number of columns specified by
     MAXCOL.  This class is suitable for reflowing a sequence of
     paragraphs.
