+ // Installation may involve executing the following programs:
+ //
+ // install
+ //
+ // GNU coreutils install recognizes the SIMPLE_BACKUP_SUFFIX and
+ // VERSION_CONTROL variables but they only matter with --backup which
+ // we do not specify and assume unlikely to be specified via .options.
+ //
+ // FreeBSD install recognizes STRIPBIN and DONTSTRIP variables that
+ // only matter with -s which we do not specify but which could be
+ // specified with .options. NetBSD and OpenBSD use STRIP (Mac OS man
+ // page doesn't list anything).
+ //
+ // sudo
+ //
+ // While sudo has a bunch of SUDO_* variables, none of them appear to
+ // matter (either not used in the modes that we invoke sudo in or do
+ // not affect the result).
+ //
+ // ln, rm, rmdir
+ //
+ // GNU coreutils ln recognizes the SIMPLE_BACKUP_SUFFIX and
+ // VERSION_CONTROL variables but they only matter with --backup which
+ // we do not specify.
