       cpif - selectively update files


SYNOPSIS

       cpif [-eq|-ne] file ...


DESCRIPTION

       cpif is an auxiliary tool for use with notangle(1) and make(1).  cpif
       compares its standard input to each of the named files, overwriting the
       file if the comparison succeeds or if the named file does not exist.
       If neither -eq or -ne is specified, the default is -ne.  Typical usage
       is in the following default rule, suitable for use in a Makefile.
        .nw.h: ; notangle -Rheader $*.nw | cpif $*.h
