cpif - selectively update files
cpif [-eq|-ne] file ...
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
