NAME

       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
