+# 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
