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 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.

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.
