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
