## 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
           annotates  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-back
           ground, deleted lines are marked with minus (`-')  charac
           ters;  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  corre
                   sponding backup-files.
