NAME
     diffpp - pretty-print diff outputs with GNU enscript


SYNOPSIS
     diffpp currentfile < diff-file


DESCRIPTION
     Diffpp converts diff(1)-program's output files to  a  format
     suitable  to be printed with GNU enscript(1).  Program anno-
     tates  the  changes  with  enscript's  special  escapes   so
     enscript  can  highlight  the modified portions of the file.
     All   changed   and   added   lines   are    printed    with
     gray-background,  deleted  lines are marked with minus (`-')
     characters; diffpp  prints  one  minus  character  for  each
     deleted line.


EXAMPLES
     The easiest way to use diffpp is  to  use  it  as  an  input
     filter  for  enscript.   If an input filter is specified for
     enscript it is used to pre-process the incoming data-stream.
     Filtering   does   not   alter   any   header   strings   or
     file-timestamps which might be printed on enscript  headers;
     only the incoming data is modified.


     enscript -G2re --filter='rcsdiff %s | diffpp %s' *.c *.h
             Print the changes between current source  files  and
             their latest RCS-versions.

     enscript -G2re --filter='diff %s~ %s | diffpp %s' *.c *.h
             Print  changes  between   source   files   and   the
             corresponding backup-files.
