Except that '-c' is always +# true and we always move an already installed target aside as +# this is important on many systems. Recent BSD install(1) +# versions have a '-b' option for this. +# +# +# OPTIONS: +# -b move previous target file aside (always true). +# +# -B "suffix" +# use "suffix" instead of .old for saving existing target. +# +# -c copy rather than move the file into place (always true). +# +# -C compare. Only install if target is missing or +# different. +# +# -N newer. Only install if target is missing or older. +# +# -s strip target +# +# -o "owner" +# make target owned by "owner" +# +# -g "group" +# make target group owned by "group" +# +# -m "mode" +# set permissions to "mode" +# +# -f "flags" +# Pass "flags" onto chflags(1) +# +# -i "errs" +# Ignore errors from steps indicated by "errs" (``s,o,g,m''). +# +# BUGS: +# The '-i' option is to save your sanity when 'bsd.prog.mk' +# insists on haveing a '-o' "owner" option which is doomed to +# fail on many systems.
