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; \f3diffpp\f1 prints one minus character for each deleted line. .SH EXAMPLES The easiest way to use \f3diffpp\f1 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. .TP 8 \f3enscript \-G2re \-\-filter='rcsdiff %s | diffpp %s' *.c *.h\f1 Print the changes between current source files and their latest RCS\-versions. .TP 8 \f3enscript \-G2re \-\-filter='diff %s~ %s | diffpp %s' *.c *.h\f1 Print changes between source files and the corresponding backup\-files. .SH SEE ALSO diff(1), enscript(1) .SH AUTHOR Markku Rossi
