DIFFPP                                            Jan 29, 1997                                         DIFFPP(1)

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-background, deleted lines are
       marked with minus (`-') characters; diffpp prints one minus character for each deleted line.

       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.
