+# Install program setuid if the installer is running as root, and if xterm is
+# already installed on the system with setuid privilege.  This is a safeguard
+# for ordinary users installing xterm for themselves on systems where the
+# setuid is not needed to access a PTY, but only for things like utmp.
+#
+# Options:
+#	u+s, g+s as in chmod
+#	-u, -g and -m as in install.  If any options are given, $3 is ignored.
+#
+# Parameters:
+#	$1 = program to invoke as "install"
+#	$2 = program to install
+#	$3 = previously-installed program, for reference
+#	$4 = final installed-path, if different from reference
